Question

Mia has 50$ on a gift card to her favorite coffee shop. Each time she visits the coffee shop sh spends $3.75 on her favorite drink. Write an equation to represent the relationship between n, the number of times she visits the coffee shop, and b, the total balance on her gift card.

Answer 1

50.00-3.75n = b

Explanation:

50.00 is the beginning balance she has on the gift card.

If she spends 3.75 every visit, and n represents the number of visits, then 3.75n will tell you how much she has spent with each visit.

1 visit: 50.00 - 3.75(1) = 46.25

2 visits: 50.00 - 3.75(2) = 42.50

3 visits: 50.00 - 3.75(3) = 38.75
