A person will save 7.32 by buying 15.25 regular gallons instead of premium gallons.
Step-by-step explanation:
Given,
Cost of regular gasoline = 2.899
Cost of premium gasoline = 3.379
Difference = 3.379 - 2.899 = 0.48
A person will save 0.48 on each gallon of gasoline.
Number of gallons = 15.25 gallons
Amount saved on 15.25 gallons = Total gallons * Amount saved on each gallon
Amount saved on 15.25 = 15.25*48 = 7.32
A person will save 7.32 by buying 15.25 regular gallons instead of premium gallons.
