Question
) Today, it is 2025 and Uber is planning on purchasing 500 self-driving cars for the San Francisco market. They have their choice of two models, a Tesla and a GM. Each Tesla costs $75,000 and has maintenance expenses of $5,000 a year because of the heavy use they receive. The GM only costs $60,000, but has maintenance expenses of $6,000 per year. The Tesla is expected to have a productive life of 5 years, after which it will have a salvage value of zero. (The battery disposal is very expensive) The GM is expected to have a productive life of 3 years with zero value afterwards. Each car will be depreciated straight-line over its productive life to a zero salvage value. Uber's marginal tax rate is 40% and the appropriate discount rate is 13%. Which car should they choose?

Explanation / Answer
Calculation of Equated annual cost per year :
75000-10551.69
64448.31
60000-10389.06
49610.94
64448.31/3.51723
18323.60
49610.94/2.36115
21011.35
since the equated cost of TElSA is lower than GM ,Telsa should be purchased.
***Calculation is done for one car ,all cost should be multiplied by 500 to get amount for 500 cars .
Telsa GM Initial cost 75000 60000 Depreciation per year [cost /useful life] 75000/5 = 15000 60000/3=20000 Annual cost 5000+15000= -20000 [since it is cost (cash outflow)] 6000+20000=-26000 After tax annual cost [annual cost (1-tax)] -20000[1-.40] = -12000 -26000[1-.40]= -15600 Annual cash flow [after tax cost+ depreciation] -12000+15000 =3000 -15600+20000= 4400 present value of cash inflow PVA 13%,5 *Annual cash inflow PVA 13%,3 *Annual cash flow 3.51723*3000 2.36115*4400 10551.69 10389.06 Net cost of cAr [initial cost - present value of cash inflow]75000-10551.69
64448.31
60000-10389.06
49610.94
equated annual cost [net cost /PVA@ 13%,n]64448.31/3.51723
