Let x represent the number of miles.
For Car Stars Auto Rental, the total cost for one day is $35 + $0.25x
For Car Express Auto Rental, the total cost for one day is $17 + $0.40x
Setting the two costs equal to each other:
35 + 0.25x = 17 + 0.40x
18 = 0.15x
x = 120
Therefore, the same cost for one day would occur at 120 miles.
