Divide the price by the number of ounces to get the price per ounce.
A. 1.69 / 18 = $0.09 per ounce
I am sorry! But thank you Ms. Sue!
You're welcome, Lycia. :-)

14 ounce for$1.71
28 ounce for $2.94
24ounce for $2.57
34 ounce for$3.30
I picked a because it is the cheapest jar of peanut butter
To determine which jar of peanut butter is the best buy, you can calculate the price per ounce. The lower the price per ounce, the better the deal.
To calculate the price per ounce, you need to divide the total price of the jar by the number of ounces it contains. Let's calculate the price per ounce for each option:
A. 18 oz jar for $1.69:
Price per ounce = $1.69 / 18 = $0.0944 per ounce
B. 30 oz jar for $2.59:
Price per ounce = $2.59 / 30 = $0.0863 per ounce
C. 32 oz jar for $2.89:
Price per ounce = $2.89 / 32 = $0.0903 per ounce
D. 24 oz jar for $2.09:
Price per ounce = $2.09 / 24 = $0.0871 per ounce
Now that you have calculated the price per ounce for each option, you can see that option B, the 30 oz jar for $2.59, has the lowest price per ounce at $0.0863. Therefore, the 30 oz jar for $2.59 is the best buy in terms of price per ounce.
