Question

A 12.5 oz bag of chips for $3.79 or a 3 oz bag for $1.00. Tell me the unit rate and which is the better buy.

Answer 1

The unit price for the 12.5 oz bag of chips is $0.3032 per ounce, while the unit price for the 3 oz bag is $0.3333 per ounce. Since the unit price is lower for the larger bag, the 12.5 oz bag of chips is the better buy.

Step-by-step explanation:

To determine which bag of chips provides the better buy, you must calculate the unit price for each option. The unit price is the cost per ounce for each bag.

For the 12.5 oz bag at $3.79, the unit price is calculated as follows:

1. Divide the total cost by the number of ounces: $3.79 ÷ 12.5 oz = $0.3032 per ounce.

For the 3 oz bag at $1.00, the unit rate is:

1. Divide the total cost by the number of ounces: $1.00 ÷ 3 oz = $0.3333 per ounce.

Comparing the two unit prices:

• 12.5 oz bag: $0.3032 per ounce
• 3 oz bag: $0.3333 per ounce

Since $0.3032 per ounce is less than $0.3333 per ounce, the 12.5 oz bag of chips is the better buy.
