You can put this solution on YOUR website! if you buy a car wash at the gas station for $5.00, the cost per gallon is $3.10. if you have $40, write and solve a linear equation to find the number of gallons of gas you can afford.
------------------
g = (40-5)/3.1 = 35/3.1 = 11.29 gallons if you get a car wash
-----
g = 40/3.1 = 12.9 gallons if you do not get a car wash
------------
