Question

A coffee shop sells refill mugs for $7.50 each. Each coffee refill costs $1.75. Last month, Cody spent $42.50 on a mug and refills. Which equation can you use to find how many refills Cody bought. (Let x = the number of refills) How many refills did Cody buy last month? 10, 12, 20, or 25

Answer 1

cannot see equations to select from but I got '7.50 + 1.75x = 42.50'

20 refills

Explanation:

7.50 + 1.75x = 42.50

1.75x = 35

x = 35 / 1.75

x = 20
