Natalie is thinking of buying a van that will be used only for business. The cost of the van is estimated at $36,500. Natalie would spend an additional $2,500 to have the van painted. In addition, she wants the back seat of the van removed so that she will have lots of room to transport her mixer inventory as well as her baking supplies. The cost of taking out the back seat and installing shelving units is estimated at $1,500. She expects the van to last about 5 years, and she expects to drive it for 200,000 miles. The annual cost of vehicle insurance will be $2,400. Natalie estimates that at the end of the 5-year useful life the van will sell for $7,500. Assume that she will buy the van on August 15, 2019, and it will be ready for use on September 1, 2019.

Natalie is concerned about the impact of the van’s cost on her income statement and balance sheet. She has come to you for advice on calculating the van’s depreciation.

Q1. Determine the cost of the van.

Q2. Prepare three depreciation tables for 2019, 2020, and 2021: one for straight-line depreciation (similar to the one in Illustration 9-10), one for double-declining balance depreciation (Illustration 9-14), and one for units-of-activity depreciation (Illustration 9-12). For units-of-activity, Natalie estimates she will drive the van as follows: 15,000 miles in 2019; 45,000 miles in 2020; 50,000 miles in 2021; 45,000 miles in 2022; 40,000 miles in 2023. Recall that Cookie Creations has a December 31 year-end

Q3. What impact will the three methods of depreciation have on Natalie’s balance sheet at December 31, 2019? What impact will the three methods have on Natalie’s income statement in 2019?

Match the following with Straight Line, Double Declining, or Units of Activity

Lowest amount of Net income

Lowest amount of stockholders' equity

lowest net book value

greatest amount of net income

greatest amount of stockholders equity

greatest book value

Creating a Kilometer to Miles Converter

Graphical User Interaction is the way of our world today as we know it. This week you will have an opportunity to design and develop perhaps your first GUI app.

Lab Assignment Objectives

1. Understand the basics of tkinter GUI development.
2. Based on an informal application specification be able to develop a tkinter GUI program that contains one or more Label widgets.
3. Be able to prompt user for input to a GUI application using a messagebox.
4. Obtain user input into a GUI application that can be used for event driven selection.
5. Be able to develop a tkinter GUI program that supports event-based widgets.
6. Develop a tkinter GUI program that maintains application state using a Canvas widget and/or a Frame widget to pack other widgets.

Understand the Application

For this GUI app you will create a kilometer to miles distance converter. Specifically we will write a class that will implement converting distances in kilometers to miles.

Implement a GUI app that contains:

• a text entry for the user to provide a kilometer input
• two buttons labeled "Convert" and "Quit"

Invoking the app, the user will be able to supply a kilometer value into the kilometer entry widget prompt.

When the user clicks the first button, Convert, the kilometers to miles conversion result will be displayed in an information dialog box. When the user clicks the second button, Quit, the app closes.

The Program Specification

Write a program that converts distances in kilometers to miles. The task for this lab is to develop an Object Oriented GUI application as a class that encapsulates the implementation of converting distances in kilometers to miles. Display the result in an info dialog box.

Testing Specification

Create an instance of the Kilometer Converter GUI class to demonstrate your app.

Input Error Checking: Validate user Input into the entry widget (i.e. a valid kilometer value). Do check that the button clicked performs the correct action (i.e. the convert button invokes the callback function for the conversion, the quit button closes the app).

Test Run Requirements: Provide a screenshot of your GUI program console display.

Hybrid cars are touted as a "green" alternative; however, the financial aspects of hybrid ownership are not as clear. Consider the 2014 Edsel 550h, which had a list price of $5,500 (including tax consequences) more than the comparable Edsel 550. Additionally, the annual ownership costs (other than fuel) for the hybrid were expected to be $470 more than the traditional sedan. The EPA mileage estimate was 26 mpg for the hybrid and 18 mpg for the traditional sedan.

a. Assume that gasoline costs $3.80 per gallon and you plan to keep either car for six years. How many miles per year would you need to drive to make the decision to buy the hybrid worthwhile, ignoring the time value of money? (Do not round intermediate calculations and round your answer to nearest whole number, e.g., 32.) Miles per year: ???

b. If you drive 17,500 miles per year and keep either car for six years, what price per gallon would make the decision to buy the hybrid worthwhile, ignoring the time value of money? (Do not round intermediate calculations and round your answer to 2 decimal places, e.g., 32.16.) Price per gallon $ ??

c. Gasoline costs $3.80 per gallon and you plan to keep either car for six years. How many miles per year would you need to drive to make the decision to buy the hybrid worthwhile? Assume the appropriate interest rate is 10 percent and all cash flows occur at the end of the year. (Do not round intermediate calculations and round your answer to the nearest whole number, e.g., 32.) Miles per year: ??

d. If you drive 17,500 miles per year and keep either car for six years, what price per gallon would make the decision to buy the hybrid worthwhile? Assume the appropriate interest rate is 10 percent and all cash flows occur at the end of the year. (Do not round intermediate calculations and round your answer to 2 decimal places, e.g., 32.16.) Price per gallon $??

(Using C++ create a Car Instrument Simulator)

Car Instrument Simulator

Create the following classes: Car, Odometer, FuelGauge.

The Car class allows for the instantiation of a Car object.

The Car object will contain (via composition) an Odometer object, and a FuelGauge object.

The Car object will also include "make", "model", and "color" as string properties (instance variables).

In the Car constructor method, you will create a FuelGauge object, passing 15 as an argument into the FuelGauge constructor indicating the number of gallons.

In the Car constructor method, you will create an Odometer object, passing 0 and the address of the FuelGauge object as arguments to the Odometer constructor, indicating the number of miles driven and the address of the FuelGauge object respectively.

The Car class will have a "drive(int miles)" method.

The Odometer object will contain a pointer to a FuelGauge object.

The Odometer object will contain a "milesDriven" instance variable.

The Odometer object will have an "incrementMileage()" method.

The implementation of the Odometer incrementMileage method will be such that if the fuel level is greater than zero, the Odometer increments its mileage instance variable by 1. Also, at every interval of GAS_MILEAGE (a constant that specifies the miles per gallon), and if the FuelGauge's fuelLevel is greater than zero, the Odometer will call the decreaseFuelLevel() method on the FuelGauge object.

The FuelGauge object will have a "decreaseFuelLevel()" method.

The FuelGauge object will contain a "fuelLevel" instance variable.The FuelGauge object will have a "getFuelLevel()" method that returns the current value of the fuelLevel instance variable.

The FuelGauge object will have a "decreaseFuelLevel(int gallons)" method.

The implementation of the FuelGauge decreaseFuelLevel method will be such that the FuelGauge decrements the fuelLevel instance variable by the specified number of gallons. Do not decrease the fuelLevel to a negative value.

The implementation of the Car "drive(int miles)" method will be such that it has a loop wherein...

while you've driven less then the number of miles specified by the "drive" method parameter value (make it 500) and the fuel level is greater than zero,call the incrementMileage method on the Odometer object.

When the car stops driving because it has run out of fuel, display the number of miles driven.

1)      Surrounding the Great Lake are four paper-mills, each producing 100 tons of paper per year. The paper is sold on the national market for $2 per ton, and including all the costs of production, costs for each firm are $1 per ton. Thus each firm earns a pure economic profit of $1 per ton. These paper mills require fresh water to operate and also produce a pollutant, which they dump into the Great Lake. New paper mills can also locate on the Great Lake, and produce at a base cost of $1 per ton. However, for each new paper mill which arrives (i.e., starting with the 5th mill), the water will become more polluted, and each firm will have to install a water treatment facility to obtain fresh water. This externality associated with new plants will raise the costs of paper production at all facilities, including the new one, by $.15 per ton for each new mill.

a. Fill in the table below to help you with your answers. which compares average revenues with average and marginal costs as new firms locate around the lake. (2 points)

b. Assume there is free access to the Great Lake. If paper mills will continue to locate as long as their is any economic profit to be earned, how many new mills will be built (i.e., the open access solution? (2 points)

c. What is the number of mills that maximizes total combined profits for the paper producers? (Hint: Average revenue remains constant at $2 (i.e, the efficient solution)?. What are these profits (resource rents) if the efficient solution? (2 points)

d. Suppose that government regulation reduced the number of mills by one from the number that would have resulted given free access. Show that the increase in profits to the remaining firms (the resource rent) is sufficient to compensate the firm that is denied access its lost profits. (2 points)

2) Suppose the state is trying to decide how many miles of a scenic river it should preserve. There are 100 people in the community, each of whom has an identical inverse demand function given by P=10-1.0q, where q is the number of miles preserved and P is the per-mile-price he or she is willing to pay for the q miles of preserved river. If the marginal cost of preservation is $500 per mile, how many miles would be preserved in an efficient allocation? (2 points)

1) Golf-course designers have become concerned that old courses are becoming obsolete since new technology has given golfers the ability to hit the ball so far. Designers, therefore, have proposed that new golf courses need to be built expecting that the average golfer can hit the ball more than 255255 yards on average. Suppose a random sample of 135 golfers be chosen so that their mean driving distance is 252.5 yards. The population standard deviation is 42.6 Use a 5% significance level.

The city of​ Belgrade, Serbia, is contemplating building a second airport to relieve congestion at the main airport and is considering two potential​ sites, X and Y. Hard Rock Hotels would like to purchase land to build a hotel at the new airport. The value of land has been rising in anticipation and is expected to skyrocket once the city decides between sites X and Y.​ Consequently, Hard Rock would like to purchase land now. Hard Rock will sell the land if the city chooses not to locate the airport nearby. Hard Rock has four​ choices: (1) buy land at​ X, (2) buy land at​ Y, (3) buy land at both X and​ Y, or​ (4) do nothing. Hard Rock has collected the following data​ (which are in millions of​ euros):                                                                                       Site X Site Y Current purchase price 26 22 Profits if airport and hotel built at this site 50 40 Sale price if airport not built at this site 12 7 Hard Rock determines there is a 50​% chance the airport will be built at X​ (hence, a 50​% chance it will be built at​ Y).
