She estimates the department will save $20,000.00 a year by having the new cars. The cars will cost the city $200,000.00. Unfortunately, the life span of a police car is only four years at best.Using a 7% discount rate, calculate the net present value of the proposal. Explain the results.

Discount rate =
Cost of cars =
Annual Savings =
Life span =
