Problem
A new six-speed automatic transmission for automobiles offers an estimated 4% improvement in fuel economy compared to traditional fourspeed transmissions in front-wheel drive cars. If a four-speed transmission car averages 30 miles per gallon and gasoline costs $4.00 per gallon, how much extra can a motorist pay for a fuel-efficient six-speed transmission? Assume that the car will be driven for 120,000 miles over its lifetime of 10 years. The motorist can earn 6% per year on investments.
