Amy received a $90 gift card for a coffee store. She used it in buying some coffee that cost $8.64 per pound. After buying
the coffee, she had $55.44 left on her card. How many pounds of coffee did she buy?

Amy bought 4 pounds of coffee.

Step-by-step explanation:

To begin, subtract what she has left, $55.44, from what she began with with, $90. That equation looks like: 90 - 55.44 = 34.56

Now divide $34.56 by the cost of each pound of coffee, $8.64. That equation looks like: 34.56 ÷ 8.64 = 4

So your answer is 4. Amy bought 4 pounds of coffee.
