Spot-Free Car Wash is considering a new project whose data are shown below. The equipment to be used has a 3-year tax life, would be depreciated on a straight-line basis over the project's 3-year life, and would have a zero salvage value after Year 3. No new working capital would be required. Revenues and other operating costs will be constant over the project's life, and this is just one of the firm's many projects, so any losses on it can be used to offset profits in other units

What would the NPV be if the annual number of cars washed declined to 58% of it's expected level(and it remained at that level for the following 3 years)?

Project cost of capital (r) 10.0%

Net investment cost (depreciable basis) $60,000

Number of cars washed 2,800

Average price per car $25.00

Fixed op. cost (excl. deprec.) $10,000

Variable op. cost/unit (i.e., VC per car washed) $5.38

Annual depreciation $20,000

Tax rate 35.0%
