Are you thinking of bypassing a gasolinefueled car in favor of a hybrid (gasoline and electric) automobile? Let's take a look at the relative economics of your possible choice. The gasoline-fueled car sells for $20,000 and gets 25 miles per gallon (mpg) of fuel. The alternative hybrid vehicle sells for $24,000 and averages 35.2 mpg. The resale value of the hybrid car is $2,500 more than that of the gasoline-only car after five years of anticipated ownership. If you drive 16,000 miles per year and gasoline costs $4.00 per gallon, what is the internal rate of return on the incremental investment in the hybrid automobile?
