Sarah drove 228 miles using 9.5 gallons of gas. how many more gallons will she use if she goes 336 more miles?

14 gallons

Step-by-step explanation:

First determine the amount of miles per gallon her car will go by dividing the amount of miles by the amount of gallons.

228/9.5 = 24 miles per gallon

This means on a trip of 336 miles she will use 14 gallons.

336/24 = 14 gallons
