Question

Deandre paid $10.47 for a 6.08-kg bag of dog food. A few weeks later, he paid $13.88 for a 7.48-kg bag at a different store. Find the unit price for each bag. Then state which bag is better buy based on the unit price. Round your answer to the nearest cent.

Answer 1

$10.47 for a 6.08 kg bag of dog food.

$13.88 for a 7.48 bag

Unit price = cost / kg

Store A

Unit price = 10.47 / 6.08 = $ 1.72 per kg

Store B

Unit price = 13.88 / 7.48 = $1.86 per kg

Based on unit price Store A ( the first one ) has a cheaper price ( $1.72 < $1.86 )

So, it is better to buy at the first store.
