Bot GPT 4-o mini To determine which jar of peanut butter is the best buy, we need to calculate the cost per ounce for each jar.
-
12 ounces for $1.48
Cost per ounce = \( \frac{1.48}{12} \approx 0.1233 \) dollars per ounce -
24 ounces for $2.69
Cost per ounce = \( \frac{2.69}{24} \approx 0.1129 \) dollars per ounce -
26 ounces for $2.81
Cost per ounce = \( \frac{2.81}{26} \approx 0.1085 \) dollars per ounce -
40 ounces for $3.76
Cost per ounce = \( \frac{3.76}{40} = 0.094 \) dollars per ounce
Now, we summarize the cost per ounce for each option:
- 12 ounces: $0.1233 per ounce
- 24 ounces: $0.1129 per ounce
- 26 ounces: $0.1085 per ounce
- 40 ounces: $0.094 per ounce
The best buy is the jar with the lowest cost per ounce. Therefore, the 40-ounce jar at $3.76, with a cost of $0.094 per ounce, is the best buy.
