A car rental company charges customers based on the equation C(m) = .25m + 30, where C(m) represents the total cost, and m represents the number of miles driven by the customer. Explain what the numbers .25
and 30 mean in the context of the problem.

The number 0.25 represents $0.25 per mile and 30 would represent a $30 flat rate (mandatory payment).

Explanation:
Car rental companies usual charge a certain amount per mile the renter drives the car including a flat rate. So here is what all the equations terms mean...
• C(m) = total cost to rent a car
• .25 = how many each mile costs
• m = how many miles the renter will drive or has driven
• + = add together
• 30 = flat rate to rent a car
