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)

Answer 1

1.75x-7.50=42.50 then you would simplify to find x

Answer 2

42. 50 = 7.50x + 1.75

5.43
