Question

Jasmine is thinking about buying a car and is comparing two vehicles. One gets 13 miles to the gallon (mpg) and the other agents 26 miles to the gallon. Assuming that she drives 5,000 miles a year, how much money would she save by buying the more fuel efficient car if gas is $3 a gallon?

Answer 1

$576.93

Explanation:

Car A

13 miles to the gallon (mpg)

13 miles = 1 gallon

Car B

26 miles to the gallon

26 miles = 1 gallon

Car B is more fuel efficient than car A

1 gallon = $3

Assuming that she drives 5,000 miles a year

Cost of buying Car A

5000 miles / 13 miles × $3

= 384.62 × 3

= $1,153.86

Cost of buying car B

5000 miles / 26 miles × $3

= 192.31 × 3

= $576.93

Car A - car B

= $1,153.86 - $576.93

= $576.93

Jasmine will save $576.93 by buying the more fuel efficient car if gas is $3 per gallon
