Keiko received an $80 gift card for a coffee store. she used it in buying some coffee that cost $8.04 per pound. after buying thr coffee, she had 31.76 left her card. how many pounds of coffee did she buy?

6 pounds of coffee.

Step-by-step explanation:

First, we determine how much money she spent. 80-31.76 = 48.24

Next, we divide the money spent by the price per unit. 48.24/8.04=6

Therefore, she bought 6 pounds of coffee.

Hey there!!

Let's take the amount of pounds as 'p'

The cost for each pound is $8.04

Total amount of money is $80

The amount of money left is $31.76

Total amount of money left = Total amount of money - money spent on the coffee.

... 31.76 = 80 - 8.04p

... -48.24 = -8.04p

... 6 = p

Hence, the total number of pounds taken is "6".
