Answer:
11 gallons of gas
Step-by-step explanation:
We can first start by subracting 5 from 40, because we have already saved that for a car wash. This leaves us with 35 dollars remaining. We will then have to do division, because we are trying to find the gallons of gas. We can consider the equation 3.1x=35 which means we can only buy 11 gallons.
