a rental car costs $25 plus a fixed charge per mile driven. The total charge for 210 miles of use was $67. Write an equation for the cost, C (in dollars), in terms of the miles driven, X.

First, we need acknowledge that 25 is the fixed number.

67 - 25 = 42

210/42 = 5

This means that 5$ is charged every mile.

Thus, we obtain

C = 25 + 5x
