22,000

Salvage Value (in year 5)

10,000

7,000

Miles per Gallon

50

30

Cost of fuel (per Gallon)

4.00

4.00

What’s the minimum average number of miles per year that you have to drive in order for the Hybrid to be more economical?

a.) Ignore inflation and assume MARR=0.

b.) Ignore inflation. Now assume MARR=7%.

Explanation / Answer

Fuel cost = (35000 / 50) * 4 = $ 2800

Purchase cost = 35000

BEP = (35000 + 2800) / 50

         = 756 miles
