Question

A bike rental service charges a $23.50 initial flat rate and then an additional $5.40 per hour. Write an equation in the slope-intercept form where x represents the number of hours of the rental, and y represents the total cost of the rental.

Answer 1

y = 5.4x + 23.5

Explanation:

Since the service charges $23.50 for every hour, you have to multiply x by 23.5 like this: 23.5

There is a flat fee of $23.50, so you have to add 23.5 on top of that like this: 5.4x + 23.5

All of this has to add up to y; 5.4x + 23.5 = y
