Amy received a $80 gift card for a coffee store. She used it in buying some coffee that cost $8.17 per pound. After buying the coffee, she had $55.49 left on her card. How many pounds of coffee did she buy?

Pretty sure the answer is 3 pounds you can pretty much repeatedly take away 8.17 from 80 till you get 55.49

80 - 8.17 = 71.83

71.83 - 8.17 = 63.66

63.66 - 8.17 = 55.49

so 3 Pounds since you took 8.17 three times to get 55.49

1/800 is the right answer
