Question

Toyota will bring hybrid electric automobiles to market next year priced at ​$27 comma 000 ​(this includes a ​$6 comma 750 federal tax​ credit). At ​$1.89 per gallon of​ gasoline, it will take 11 years to recoup the difference in price between a base model Toyota Camry and its​ four-cylinder gasoline-only counterpart. The price difference is ​$4 comma 180. If the hybrid vehicle is driven for 15 ​years, what is the internal rate of return on the extra investment in the​ hybrid?

Answer 1

4.15%

Step-by-step explanation:

In order to determine the annual saving we must divide the extra cost of the hybrid by the amount of years it takes to recoup our investment.

annual savings = $4,180 / 11 years = $380 per year

our initial investment = -$4,180

since we are going to use the car during 15 years, then we have 15 positive cash flows of $380

using a financial calculator or excel spreadsheet, the internal rate of return (IRR) on our investment = 4.15%
