To determine which is the better buy, we need to compare the prices per ounce of each option.
For the first option:
Price: $2.24
Amount: 28 ounces
Price per ounce = Price / Amount
Price per ounce = $2.24 / 28 ounces
Price per ounce ≈ $0.08
For the second option:
Price: $2.40
Amount: 32 ounces
Price per ounce = Price / Amount
Price per ounce = $2.40 / 32 ounces
Price per ounce = $0.075
Comparing the two price per ounce values, we can see that the second option has a lower price per ounce ($0.075) compared to the first option ($0.08).
Therefore, the second option, which is 32 ounces of peanut butter for $2.40, is the better buy because it has a lower price per ounce.
To determine which is the better buy, we need to compare the cost per ounce of peanut butter for each option.
For the first option, the store sells 28 ounces of peanut butter for $2.24. We can calculate the cost per ounce by dividing the total cost ($2.24) by the number of ounces (28):
Cost per ounce for option 1 = $2.24 / 28 = $0.08 per ounce
For the second option, the store sells 32 ounces of peanut butter for $2.40. Similarly, we can calculate the cost per ounce by dividing the total cost ($2.40) by the number of ounces (32):
Cost per ounce for option 2 = $2.40 / 32 = $0.075 per ounce
Now that we have both costs per ounce, we can compare them.
The cost per ounce for option 1 is $0.08, while the cost per ounce for option 2 is $0.075.
Since the cost per ounce for option 2 is lower than option 1, the second option is the better buy.
