The president of Lowell Inc. has asked you to evaluate the proposed acquisition of a new computer. The computer's price is $60,000, and it falls into the MACRS 3-year class (33% in year 1, 45% in year 2, 15% in year 3, and 7% in year 4). Purchase of the computer would require an increase in net operating working capital of $2,000. The computer would increase the firm's before-tax revenues by $20,000 per year but would also increase operating costs by $5,000 per year. The computer is expected to be used for 4 years and then be sold for $25,000. The firm's marginal tax rate is 40 percent, and the project's cost of capital is 14 percent. What is the net investment required at t = 0?

a. -$42,000

b. -$62,000

c. -$38,600

d. -$37,600

e. -$36,600
