Jina received a $70 gift cards for a coffee store. She used it in buying some coffee that cost $8.64 per pound. After buying the coffee, she had $26.80 left on her card. How many pounds of coffee did she buy?

Respuesta :

Answer:

If I'm correct she bought 5 pounds of coffee.

Step-by-step explanation:

$70 (gift card)

-$26.80 (remainder on g.c.)

= $43.20 ($ spent on money)

$43.20/ $8.64 = 5

(remainder)/ cost per lb. = lbs of coffee bought
