A new shoe production line is being designed at a cost of $245,000 and operating costs are
expected to be $84,000 per year. Planned annual production is 2500 pairs and the price of a pair of
shoes is $110. The line's service life is 14 years, the
rate for the base case. Using the interval [-20%, -10%, +10%, +20%], perform a present worth
sensitivity analysis using a sensitivity graph with respect to the following variables in terms of their
impact on the Present worth.
a) First Cost
b) Operative cost
c) Annual Production
d) Salvage Value

- 4. A 3-year-old manufacturing equipment, which has a present market value of $13,000, is being considered for early replacement. The estimated five-year market values and annual operating costs are shown below. The AW replacement values of year 1 and 2 have already been conducted, help the company determine the total AW3 replacement value (year 3 only) which will consider how long the asset should be retained, its ESL.

The cockroach eradicator project will require $2,100,000 in net working capital to start, and total net working capital will rise to 15% of the change in sales. The variable cost per unit is $340, and total fixed costs are $2,400,000 per year. The equipment necessary to begin production will cost a total of $22 million. This equipment is mostly industrial machinery and thus qualifies for CCA at a rate of 20%. In five years, this equipment will actually be worth about 20% of its cost. The relevant tax rate is 35%, and the required return is 16%. Based on these preliminary estimates, what is the NPV of the project? (Enter the answer in dollars.
