Question

Charlie paid $15.48 for a 7.48 - bag of dog food. A few weeks later, he paid $16.58 for a 7.94-kg bag at a different store.
Find the unit price for each bag. Then state which bag is the better buy based on the unit price.

Round your answers to the nearest cent.

To find the unit price, we divide the cost by the weight of each bag:

For the first bag:
Unit price = 15.48 ÷ 7.48 = $2.07 per kilogram

For the second bag:
Unit price = 16.58 ÷ 7.94 = $2.09 per kilogram

Based on the unit price, the first bag is the better buy as it is cheaper per kilogram.
