Jessica received a 90$ gift card for a coffee store. She used it in buying some coffee that cost 8.58per pound. After buying the coffee, she had 47.10 left on her card. How many pounds of coffee did she buy?

5 pounds / Make sure to read the explanation so you know how to solve it

Step-by-step explanation:

First thing to do is:

Subtract 90 by 47.10 to find the amount of money she spent

She spent $42.90 on coffee and we know that it costs $8.58 per pound so that means that we should divide 42.90 by the cost per pound:

She bought 5 pounds of coffee

Hope I helped :]
