Kira received a S90 gift card for a coffee store. She used it in buying some coffee that cost $7.28 per pound. After buying the coffee, she had 553.60 left on
her card. How many pounds of coffee did she buy?
This question is not valid because the gift card is only 90 pounds. You states that the Coffee she bought was 553 dollars. This means she will have negative profit, therefore this question is not states correctly.
