I need solution for Problem 3. Thank you !

Problem 3: Electric Vehicles and Discounting [2.5 points] Consider the choice of buying one of two cars: an electric vehicle (EV), which costs $60,000, and a plug-in hybrid electric vehicle (PHEV), which costs $50,000. Suppose you expect to own the vehicle until the end of the 9th year and that you will save $1,000 per year in gasoline expenditures if you buy the EV. Further suppose that the annual real interest rate for a savings account is r = 2%. For simplicity, assume there is no resale value for either car and that you receive your gasoline savings annually starting immediately (i.e., today). 3.A. [0.5 points] Which vehicle provides a better return on investment? By how much? 3.B. [1 point] How many years will it take for the two investments to be equal? 3.C. [1 point] Now suppose that you expect gasoline savings to increase at an annual rate of o = 10%. Would this rate justify buying an EV
