Question

Linda needs to have her car towed. Little Town Auto charges a flat fee of $60 plus per mile towed. Write a function expressing Linda's towing cost, C, in terms of miles towed, x. Find the cost of having a car towed 3 miles.

Answer 1

 

Let m = cost, per mile

Let x = number of miles towed

 

C(x) = mx + 60

 

The cost of having a car towed 3 miles is:

 

   C(3) = 3m + 60
