How would I solve using excel? Please provide the formula.

Florida 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 change in net operating working capital would be required. Revenues and oth life, and this is just one of the firm's profits in other units. If the number of cars washed declined by 40% from the expected level, by how much would the project's NPV change? (Hint: Note that cash flows are constant at the Year 1 level, whatever that level is.) er operating costs will be constant over the project's s many projects, so any losses on it can be used to offset WACC Net investment cost (depreciable basis) Number of cars washed Average price per car Fixed oper. costs (excl. depreciation) Variable oper. cost/unit (i.e., VC per car washed) Annual depreciatiorn Tax rate 10.0% $60,000 2,800 $25.00 $10,000 S5.375 $20,000 35.0%
