Question

Kayla received a $90 gift card for coffee. She used it in buying some coffee that cost $8.24 per pound. After buying the coffee, she had $57.04 left on her card. How many pounds of coffee did she buy?

Answer 1

Kayla has $90 originally, and ends up with $57.04. That means that she spent $32.96. Now divide. 
32.96 / 8.24 = 4.

Kayla bought 4 pounds of coffee.
