Cost is $40 + .22*m where m is the miles


You can pay a maximum of $84.


formula is:


84 = 40 + .22*m


subtract 40 from both sides of this equation to get:


44 = .22*m


divide both sides of this equation by .22 to get:


44/.22 = m


simplify to get:


m = 200


you can go at most 200 miles assuming there are no additional charges like taxes, gas, insurance, etc.
