Question

Your car breaks down on the highway, and you need to have it towed to a garage. A towing company charges $50 plus $4 per mile. If the bill was $138, how far were you towed? Explain.

Answer 1

22 miles

Explanation:

Given data

A towing company charges $50 plus $4 per mile

let the number of miles be x

the expression for the charges for x miles y is given as

y= 50+4x

for y= 138

138= 50+4x

138-50= 4x

88= 4x

x= 88/4

x= 22 miles

Hence the distance is 22 miles
