Carmen received an $80 gift card for a coffee store. She used it in buying some coffee that cost $7.74 per pound. After buying the coffee, she had $33.56 left on her card. How many pounds of coffee did she buy?
First find out how much money she spent by doing 80 (original amount) - 33.56 (amount after spending): $46.44 Now she spent 46.44 dollars and each pound is 7.74: 46.44 / 7.74 = 6 She bought 6 lbs
