Question

A clothing

store offers a rewards program in which customers earn points by making purchases at the
store. Every item bought is worth 8 points, and customers earn 20 points when they sign up. Write an
equation for the function that gives the number of points based on the number of items bought. How
many points will a customer have after making 16 purchases?

Answer 1

Equation for the function: y=8x+20

Explanation:

8 represents points per item/rate of change

20 represents the y intercept or what the person gains in the beginning that doesn't change.

8(16)+20

128+20

=148

After making 16 purchases the person will have 148 points.
