Diane received a $80 dollar gift card for a coffee store. She used it in buying some coffee that cost $8.14 per pound. After buying the coffee, she had $39.30 left on her card. How many pounds of coffee did she buy?
5 pounds Because you have to subtract $80 from $39.30 and when you do that you get $40.70. Then you divide that by the $8.14 per pound and that gives you your answer.
Take 80.00 and subtract the 39.30 she still has left on her gift card. That means that she spent $40.70. Take 40.70 and divide it by 8.14 per pound of coffee and you get 5. So, she bought 5 pounds of coffee
