Question

convenience store sells a 12.5-ounce big bag of potato chips for $3.79 or a 3-ounce small bag for $1.09. Which bag of chips is the better buy, the big bag or the small bag? (Remember, the better buy is the one that is cheaper per unit of product.)​

Answer 1

The big bag of chips is the better buy as it has a lower cost per ounce of $0.3032 compared to the small bag's cost per ounce of $0.3633.

Step-by-step explanation:

To determine which bag of chips is the better buy, we need to calculate the cost per ounce for each bag. For the 12.5-ounce big bag that costs $3.79, we divide $3.79 by 12.5 ounces to get the cost per ounce. For the 3-ounce small bag that costs $1.09, we divide $1.09 by 3 ounces to get the cost per ounce.

The calculations are as follows:

• Big bag: $3.79 / 12.5 ounces = $0.3032 per ounce
• Small bag: $1.09 / 3 ounces = $0.3633 per ounce

Comparing the cost per ounce of the two bags, the big bag at $0.3032 per ounce is the better buy compared to the small bag at $0.3633 per ounce, as it offers a lower cost per ounce.
