Answer 1

The cost per ounce at Giant for Jif Natural Peanut Butter is option a. $0.14, and at Weis, it is $0.16, both rounded to the nearest cent.

Step-by-step explanation:

To find the cost per ounce at each store, we need to divide the total cost of the jar by the number of ounces it contains. Then we round our answers to the nearest cent.

For the Giant store, we have a 16-ounce jar of Jif Natural Peanut Butter priced at $2.25. To calculate the cost per ounce, we do the following:

• Cost per ounce at Giant = Total cost of jar ÷ Number of ounces
• Cost per ounce at Giant = $2.25 ÷ 16 oz
• Cost per ounce at Giant = $0.140625
• Rounded to the nearest cent, the cost per ounce at Giant is $0.14/oz

For the Weis store, the jar is 40 ounces priced at $6.48. The cost per ounce is calculated as:

• Cost per ounce at Weis = Total cost of jar ÷ Number of ounces
• Cost per ounce at Weis = $6.48 ÷ 40 oz
• Cost per ounce at Weis = $0.162
• Rounded to the nearest cent, the cost per ounce at Weis is $0.16/oz

So, the correct answer is: Giant: $0.14/oz, Weis: $0.16/oz.
