Question

Hannah paid for 2.5 pounds of peanuts with a ten-dollar bill. She received $1.20 in change from the cashier. What was the price, per pound, for the peanuts?

Answer 1

$3.52

Explanation:

1. 10 - 1.20 = 8.8. Hannah had change, so you need to subtract it to find out how much she paid for 2.5 pounds.
2. 8.8/2.5 = 3.52. You are dividing to find the unit rate, which is the price of one pound.
