Jina received a 70 gift card for a coffee store. She used it in buying some coffee that cost 7.56 per pound. After buying the coffee, she had 32.20
left on her card. How many pounds of coffee did she buy?
Jina spent 70 - 32.20 = $<<70-32.20=37.80>>37.80 on coffee.
She bought 37.80 / 7.56 = <<37.80/7.56=5>>5 pounds of coffee. Answer: \boxed{5}.
