At Gas 'n' Wash, gasoline sells for $4.00 a gallon and a car wash costs $12. Helisa wants to have her car washed and keep her total purchase under $60. The inequality 4g + 12 < 60 can be used to find g, the number of gallons of gas she can buy. Determine which, if any, of these values is a solution: g = 10; g = 11; g = 12.

Victoria Gardner · Answer 1

g = 12

Step-by-step explanation:

Inequality is 4g + 12 < 60

Solving for g,

4g < 60 - 12

4g < 48

Divide both sides by 4,

g < 48 / 12

g < 12

The total amount of gas she can buy is 12 gallons
