A car rental company charges $40 per day and $0.20 per mile driven.
A customer has $160 to spend.
Write an equation and determine how many miles the customer can drive if they rent the car for 2 days.
160=40(2)+0.20m
160=80+0.20m
subtract 80 from both sides
80=0.20m
divide both sides by 0.20 and m=400
