Question

Joe paid $12.53 for a 7.03-kg bag of dog food. A few weeks later, he paid $14.64 for a 7.98-kg 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

Answer 1

Answer:

The unit price for the 7.03 kg bag is about $1.78 per kg. The unit price for the 7.98 kg bag is about $1.83 per kg. The 7.03 kg is a better deal because you pay less per kg.

Step-by-step explanation:

1) To find the unit price, you need to find the price per unit. The unit here being kg. So, you need to divide the price by the number of units.

2) Here is this written out...

7.03 kg bag:

$12.53 / 7.03 kg = 1.78236130868 dollars per kg, or about $1.78 per kg

7.98 kg bag:

$14.64 / 7.98 kg = 1.83458646617 dollars per kg, or about $1.83 per kg

3) As you can see, if Joe purchases the 7.98 kg bag of dog food, he is paying more for every kg of dog food than if he were to purchase the 7.03 kg bag of dog food. This makes the 7.03 bag of dog food a better deal.

Hopefully this helps.
