Briggs Excavation Company is planning an investment of $307,300 for a bulldozer. The bulldozer is expected to operate for 2,000 hours per year for five years. Customers will be charged $120 per hour for bulldozer work. The bulldozer operator costs $31 per hour in wages and benefits. The bulldozer is expected to require annual maintenance costing $20,000. The bulldozer uses fuel that is expected to cost $41 per hour of bulldozer operation.

a. Determine the equal annual net cash flows from operating the bulldozer. Use a minus sign to indicate cash outflows.

Feedback

a. Subtract the operating expenses (hourly fuel and labor costs, multiplied by the operating hours, plus the annual maintenance costs) from the revenues (operating hours multiplied by the hourly revenue).

b. Determine the net present value of the investment, assuming that the desired rate of return is 6%. Use the present value of an annuity of $1 table above. Round to the nearest dollar. If required, use the minus sign to indicate a negative net present value.

c. Should Briggs Excavation invest in the bulldozer, based on this analysis?
Yes , because the bulldozer cost is less than  the present value of the cash flows at the minimum desired rate of return of 6%.

d. Determine the number of operating hours such that the present value of cash flows equals the amount to be invested. Round interim calculations and final answer to the nearest whole number.

You opened an account and deposited X Dollars on January 1, 2002 in National City Bank. Any balance in the account will earn 5% per year. You withdrew $500 on January 1, 2006 and $500 on January 1, 2008. You closed out this account on January 1, 2011 and received $700. How much did you initially deposit (X) in National City at the time you opened the account?

Scheme is a dialect of a programming language called Lisp, which was developed at MIT in 1959. Alice 1.0 was released in 2006 from CMU, and Python in 1994. Based on what you know of the Scheme language, describe the major differences between how it works and how Alice or Python works. What advantages might Scheme have over Alice/Python? What advantages might Alice/Python have over Scheme?

a) Given the above widget production function information, graph the total product curve, clearly labeling everything.

b) Given the cost information above, graph the total cost curve. Add columns to the table as needed.

c) Describe the pattern of marginal returns and marginal costs. Are they related? Explain how, in detail.

d) Are we in the long run or the short run? Explain how you know.

e) What is the marginal product when eight workers are employed? How about nine? Could it ever make sense to hire the 8th worker under these conditions? The 9th?

Question 2

A research firm collected data on a sample of n = 30 drivers to investigate the relationship between the age of a driver and the distance the driver can see. The data is given below:

Use SAS to fit a simple linear regression and answer the following questions:

a) Find the least squares estimate for the regression line Y_i = b₀ + b₁X_i + e_i.

b) Estimate the standard deviation of the error term e_i
