Question

Karla drove her vehicle 12,000 miles last year. How many gallons of gasoline would she have saved last year had she driven a fuel-efficient hybrid car averaging 48 miles per gallon rather than an SVU averaging 15 miles per gallon?

Answer 1

Explanation:

so, she drove the 12,000 miles with an SUV that gave her 15 miles per gallon.

that means she used

12000 / 15 = 800 gallons of gasoline.

if she would have used a car that gave her 48 miles per gallon, she wound have needed

12000 / 48 = 250 gallons of gasoline.

so, she would have saved

800 - 250 = 550 gallons of gasoline.
