Question

Your small remodeling business has two work vehicles. One is a small passenger car used for job-site visits and for other general business purposes. The other is a heavy truck used to haul equipment. The car gets 25 miles per gallon (mpg). The truck gets 10 mpg. You want to improve gas mileage to save money, and you have enough money to upgrade one vehicle. The upgrade cost will be the same for both vehicles. An upgraded car will get 40 mpg; an upgraded truck will get 12.5 mpg. The cost of gasoline is $3.20 per gallon.

Calculate the annual fuel savings, in gallons, for the truck and car assuming both vehicles are driven 7,000 miles per year.

Answer 1

Annual fuel savings in gallons for truck=7000/10-7000/12.5=140 gallons

Annual fuel savings in gallons for car=7000/25-7000/40=105 gallons
