3. If Josie consumes 2 unit of tomatoes and 4 units of potatoes, is this a utility maximizing combination?
4. What is Josie’s optimal consumption of tomatoes and potatoes given her budget?

1. Cindy has $70 a month to spend on sport activities, and she can spend as much time as she likes playing golf and tennis. The price of an hour of golf is $20, and the price of an hour of tennis is $10. The table shows Cindy’s marginal utility from each sport.

1. If Cindy spends all her money playing golf, how many hours of golf can she afford? What will be her total utility?
2. If Cindy spends all her money playing tennis, how many hours of tennis can she afford? What will be her total utility?
3. What are the marginal utilities per dollar from playing golf and tennis for the various hours per month played?
4. How many hours of golf and tennis should Cindy play to maximize her utility given her budget?
5. Explain why, if Cindy equalized the marginal utility per hour of golf and tennis, she would not maximize her utility?
6. Cindy’s tennis club raises its price of an hour of tennis from $10 to $15, other things remaining the same, how many hours does Cindy now spend playing golf and tennis that maximizes her utility? Are there any left over money?
7. Cindy loses her math tutoring job and the amount she has to spend on golf and tennis falls from $70 to $40 a month. With the price of an hour of golf at $20 and of tennis at $10, calculate the change in the hours she spends playing golf. For Cindy, is golf and tennis a normal good or an inferior good?

Toll lanes on a section of the​ I-40 freeway are being considered in order to reduce traffic congestion and travel times. Since this is a government​ project, the​ B-C ratio method must be applied in the evaluation. The following are cost and other​ estimates:

Construction costs​ = ​$17,300,000

Operating and maintenance costs​ = ​$532,000 per year

Projected service life​ = 30 years

Savings in travel times and revenues generated from the tolls​ = ​$5,244,000 in the first year of operation and projected to increase by 2.75​% per year due to the projected annual increase in traffic. In​ addition, environmental analysis estimates that the project will result in increased noise and air pollution that will cause an additional societal health cost of ​$644,000 the first year and is also projected to increase at 2.75​% per year.

Assuming zero market​ (salvage) value at the end of 30 years and a MARR of 10​%per​ year, should the toll lanes be​constructed?

The conventional​ benefit-cost ratio of the project with PW is______​(Round to two decimal​ places.)

According to the​ B-C ratio​ method, the toll lanes should

A.not be constructed

B. be constructed

1. You are asked to price options on KYC stock. KYC’s stock price can go up by 15 percent every year, or down by 10 percent. Both outcomes are equally likely. KYC does not pay dividend. The risk free rate is 5% (EAR), and the current stock price of KYC is $100.

1. Price a European put option on KYC with maturity of 2 years and a strike price of 100.
2. Given the price of the put option that you calculated in a), specify the ranges of KYC share price at the option’s maturity date for which you will be making a net profit.
3. What is the price of the Call option at the same strike price?
4. Suppose you expect the price of KYC stock to have little variance in the future. How would you design a strategy (using options) to take advantage of this? Show your strategy explicitly. What are the payoffs of your strategy? What is the range in which you will make profits?

The operations manager at an electronics company believes that the time required for workers to build a circuit board is not necessarily proportional to the number of parts that go onto the board. She has collected data on the time (in minutes) it takes a worker to build a board and the number of parts installed. The data is in a worksheet names Circuits.   Data-1.xlsx

1. Estimate a regression line to predict time based on the number of parts.  What is the Coefficient of Determination of the simple regression? (enter as a decimal)

3. What is the standard error of the estimate of the simple regression?

4. What is the predicted time to build a circuit board with 50 parts?

5. Estimate a quadratic regression line to predict time based on the number of parts and the number of parts squared. What is the Coefficient of Determination of the quadratic model? (enter as a decimal)

6.What is the standard error of the estimate of the quadratic model?

7.

Which model is better, the simple regression or the quadratic?

Group of answer choices

a.Simple because the MSR is larger.

b. Simple because the t-statistic of Parts is much higher.

c.Quadratic because standard error is lower and adj-R² is higher.

d. Quadratic because it has two variables instead of one.
