Linkin Corporation is considering purchasing a new delivery truck. The truck has many advantages over the company’s current truck (not the least of which is that it runs). The new truck would cost $54,760. Because of the increased capacity, reduced maintenance costs, and increased fuel economy, the new truck is expected to generate cost savings of $7,400. At the end of 8 years, the company will sell the truck for an estimated $27,000. Traditionally the company has used a rule of thumb that a proposal should not be accepted unless it has a payback period that is less than 50% of the asset’s estimated useful life. Larry Newton, a new manager, has suggested that the company should not rely solely on the payback approach, but should also employ the net present value method when evaluating new projects. The company’s cost of capital is 8%.
Compute the cash payback period and net present value of the proposed investment.

#include <stdio.h>

int main() {

    int i, j;

    printf("Enter two positive integers: ");

    scanf("%d%d", &i, &j); // need to validate both being positive

    while (i != j) {

        i > j ? (i -= j) : (j -= i);

    }

    printf("GCD: %d\n", i);

    return 0;

}

The above code returns a GCD from two numbers entered. Use the above program to design

a C program to compute of integer coefficients a and b such that gcd(i, j) = a xi + b x j.

EXAMPLE RUNS:

​

Enter two positive integers: 446 39

GCD: 1 = 23 * 446 + (-263) * 39

​

Enter two positive integers: 48 112

GCD: 16 = (-2) * 48 + 1 * 112

​

Enter two positive integers: 3 2

GCD: 1 = (-1) * 3 + 2 * 2

Thank you!!

Draw the supply curve and demand curve independently in a separate graph.

Write the demand equation and the supply equation.

Combine both curves in one graph and show the equilibrium price and quantity.

What is the quantity demanded when the price is $10?

Is there a shortage or surplus when the price equals $8? What about $4?

Pole Position, a retailer at Destiny Mall, has a variable cost of $5 per lap driven. It has identified two segments of customers: Hard-Core drivers and Just-For-Fun drivers. For simplicity, throughout this problem, assume there is exactly one customer in each of the two segments. Market research has revealed how each segment values the experience, depending on how many laps are raced:

5. Suppose Pole Position had to set the price per lap the same regardless of the type of customer.

1. x
2. x
3. At this price, how many laps would a Just-For-Fun driver purchase?
4. How much profit would Pole Position earn from these sales?
5. x
6. Briefly explain why profit increases or decreases in this scenario.

08-5 Calculate and compare the hydraulic and TSS loadings (lb/d) from wastewater and stormwater for a 10-acre urban neighborhood. Assume the following:

*Wastewater: 5 houses/acre; 3.5 people/house; 50 gal/person/day; TSS = 200 mg/L

*Stormwater: 0.75 inch rainfall over 24 hours, 50% of rainfall runs off; TSS = 60 mg/L

Answer: WW load = 875 gpd, 14.6 lb/d; SW load = 101,820 gal/d, 51.0 lb/d

3. In five test runs, a truck operated 10, 12, 10, 8, and 15 miles with one gallon of gasoline. At the 98% level of confidence, is this sufficient evidence to show that the truck is operating at a mean rate of about 14 miles per gallon? A. Yes. B. No. C. Can’t be determined. D. Depends on the proportion of the tested truck

Create a C# application for Cricket Team that allows you to enter data for player of Cricket Team and saves the data to a file named Players.txt. Create a Player class that contains fields for of participant's first name, last name, age, salary and position (wicketkeeper, bawler, striker, midwicket), and To String() method. The fields of records in the file are separated with semicolon (. Expecting sentinel value for ending the process of writing to file is *. E.g. of a record in the file Players.txt: 180000;bawler

Tammi’s Truck Stop sells Seat-o-Nails cushions, which are specially designed to keep drivers awake on the road. Her accessories supplier makes deliveries every Tuesday, at which times she can get as many cushions as she wants (the supplier always has extras in his truck). Tammi, who was a statistics major in college, has done some calculations and estimates that weekly demand for cushions is normally distributed with mean 35 and standard deviation 10. The cushions cost her $40 wholesale and she sells them for $75. Tammi uses a 30 percent interest rate to evaluate the cost of holding inventory. It is Tuesday and she has 12 cushions in stock.

The supplier has just arrived. How many cushions should Tammi buy if sales are lost when she runs out of stock during the week?

How many cushions should Tammi buy if a customer who wants a cushion will still buy it when stock has run out, but she has to pay the $5 postage to mail it to the customer?
