A rental company charges $35 per day and .30 per mile your bill is 164$ how many miles did you drive

Question

How many miles did you drive

Answer 1

Fixed cost + Variable Cost = Total cost

Fixed cost + Cost per mile x number of miles driven = Total cost

Let x = number of miles you drove

Substitute into the equation

35+0.3x = 164 Now solve. Subtract 35 from both sides of the equation

0.3x = 129 Divide both sides of the equation by 0.3

0.3x = 129

x = 430 miles
