ZD&D holds a patent on a unique medical device that is used for DNA mapping. Assume that ZD&D is a single-price profit-maximizing monopolist and is currently earning positive economic profits.

(a) Draw a correctly labeled graph and show each of the following

ZD&D’s profit-maximizing price and quantity, labeled as P* and Q*.

The area representing ZD&D’s economic profits.

The allocatively efficient level of output, labeled as Qs.

(b) Instead of maximizing profit, assume that now ZD&D maximizes its total revenue.
On your graph in part (a), identify the output level that ZD&D would chose, labeled as Qr.

(c) Assume that the government imposes a set price (a price control) on ZD&D so that the allocatively efficient level of output, Qs, is produced.
On your graph in part (a), show this set price, labeled as Ps.

A small block with mass 0.0450kg slides in a vertical circle of radius 0.575m on the inside of a circular track. During one of the revolutions of the block, when the block is at the bottom of its path, point A, the magnitude of the normal force exerted on the block by the track has magnitude 3.85N . In this same revolution, when the block reaches the top of its path, point B, the magnitude of the normal force exerted on the block has magnitude 0.685N .

How much work was done on the block by friction during the motion of the block from point A to point B?

HW_7d -   Cat class

Create 3 files:

1. Cat.h
   • Include a class specification for a Cat class
   • Data members include:
     • A cat’s weight
     • A cat’s color

• Member functions (methods) include:
  • A function called setWeight, to set the cat’s weight
  • A function called setColor, to set the cat’s color
  • A function called displayInfo, that displays a cat’s age and weight on the screen
  • A function called meow, that lets the cat say “Meow” on the screen

1. Cat.cpp
   • Include the method implementations for the four functions in this file

1. Source.cpp
   • Include main()
     • In main(), declare three cats (3 cat objects)
     • Name them: Fluffy, Tom, and Kitty

• Ask the user to describe Fluffy (get Fluffy’s weight and color)

• Fluffy (the Fluffy object) calls setWeight to pass the weight to the method, where

    the weight is assigned to Fluffy’s weight.

• Fluffy (the Fluffy object) calls setColor to pass the color to the method, where

    the color is assigned to Fluffy’s color

• Repeat the above for the Tom and Kitty objects.

• Have each of the Cat objects call the DisplayInfo method to output the age and color

   of each cat.

• Have each cat say “MEOW” on the screen by having each Cat object call the

     meow method.

/* OUTPUT:

So you have three cats...

Describe Fluffy. What does she weight? 4

What color is she? brown

Describe Tom. What does he weight? 9

What color is he? orange

Describe Kitty. What does she weight? 5

What color is she? white

Fluffy weights 4 pounds and is brown.

Tom weighs 9 pounds and is orange.

Kitty weighs 5 pounds and is white.

Fluffy says: MEOW!

Tom says: MEOW!

Kitty says: MEOW!

Northwood Company manufactures basketballs. The company has a ball that sells for $25. At present, the ball is manufactured in a small plant that relies heavily on direct labor workers. Thus, variable expenses are high, totaling $15.00 per ball, of which 60% is direct labor cost. Last year, the company sold 36,000 of these balls, with the following results: Sales (36,000 balls) $ 900,000 Variable expenses 540,000 Contribution margin 360,000 Fixed expenses 263,000 Net operating income $ 97,000 Required: 1. Compute (a) last year's CM ratio and the break-even point in balls, and (b) the degree of operating leverage at last year’s sales level. 2. Due to an increase in labor rates, the company estimates that next year's variable expenses will increase by $3.00 per ball. If this change takes place and the selling price per ball remains constant at $25.00, what will be next year's CM ratio and the break-even point in balls? 3. Refer to the data in (2) above. If the expected change in variable expenses takes place, how many balls will have to be sold next year to earn the same net operating income, $97,000, as last year? 4. Refer again to the data in (2) above. The president feels that the company must raise the selling price of its basketballs. If Northwood Company wants to maintain the same CM ratio as last year (as computed in requirement 1a), what selling price per ball must it charge next year to cover the increased labor costs? 5. Refer to the original data. The company is discussing the construction of a new, automated manufacturing plant. The new plant would slash variable expenses per ball by 40.00%, but it would cause fixed expenses per year to double. If the new plant is built, what would be the company’s new CM ratio and new break-even point in balls? 6. Refer to the data in (5) above. a. If the new plant is built, how many balls will have to be sold next year to earn the same net operating income, $97,000, as last year? b. Assume the new plant is built and that next year the company manufactures and sells 36,000 balls (the same number as sold last year). Prepare a contribution format income statement and compute the degree of operating leverage.

LABOR ECONOMICS - What insight(s) does the institutional school of thought bring the study of the labor market?

Steve Sullivan was recently promoted to loan officer at the first national bank. He has authority to issue loans up to $50,000 without approval from a higher bank official. this week two small companies, Handy Harvey, Inc. and Sheila’s fashion, Inc, have each submitted a proposal for a six-month $50,000 loan. In order to prepare a financial analysis of the two companies Steve has obtained the information summarized below.

Handy Harvey, Inc. is a local lumber and home improvement company. Because sales have increased so much during the past two years, Handy Harvey has had to raise additional working capital , especially as represented by receivables and inventory. The $50,000 loan is needed to assure the company of enough working capital for next year. Handy Harvey began the year with total assets of $740,000 and stockholders equity of $260,000 and during the past year the company had a net income of $40,000 on sales of $760,000. The company’s current unclassified balance sheet appears as follows:

Sheila’s Fashions, Inc. has for three years been a successful clothing store for young professional women. The leased store is located in the downtown financial district. Sheila’s loan proposal ask for $50,000 to pay for stocking a new line professional suilts for working women during the coming season. At the beginning of the year, the company had total assets of $200,000 and total stockholders’ equity of $114,000. Over the past year, the company earned a income of $36,000 on sales of $480,000. The firm’s unclassified balance sheet the current date appears as follows

Required

1. Prepare a financial analysis of both companies’ liquidity and after receiving the proposed loan. Also, compute profitability ratios before and after as appropriate. Write a brief summary of the effect if the proposed loan on each company’s financial position.
2. To which company do you suppose Steve would be most willing to make a $50,000 loan? What are the positive and negative factors related to each company’s ability to pay back the loan in the next year? What other information of a financial or non-financial nature would be helpful before making a financial decision?

(Package Inheritance Hierarchy) Package-delivery services, such as FedEx®, DHL® and UPS®, offer a number of different shipping options, each with specific costs associated. Create an inheritance hierarchy to represent various types of packages. Use class Package as the base class of the hierarchy, then include classes TwoDayPackage and OvernightPackage that derive from Package.

Base-class Package should include data members representing the name, address, city, state and ZIP code for both the sender and the recipient of the package, in addition to data members that store the weight (in ounces) and cost per ounce to ship the package. Package’s constructor should initialize these data members. Ensure that the weight and cost per ounce contain positive values. Package should provide a public member function calculateCost that returns a double indicating the cost associated with shipping the package. Package’s calculateCost function should determine the cost by multiplying the weight by the cost per ounce.

Derived-class TwoDayPackage should inherit the functionality of base class Package, but also include a data member that represents a flat fee that the shipping company charges for two-day-delivery service. TwoDayPackage’s constructor should receive a value to initialize this data member. TwoDayPackage should redefine member function calculateCost so that it computes the shipping cost by adding the flat fee to the weight-based cost calculated by base class Package’s calculateCost function.

Class OvernightPackage should inherit directly from class Package and contain an additional data member representing an additional fee per ounce charged for overnight-delivery service. OvernightPackage should redefine member function calculateCost so that it adds the additional fee per ounce to the standard cost per ounce before calculating the shipping cost. Write a test program that creates objects of each type of Package and tests member function calculateCost.
