Final answer:
The pumpkin pie filling costs $0.18 per ounce, whereas the apple pie filling costs $0.1875 per ounce. Thus, the pumpkin pie filling is the less expensive option per ounce.
Step-by-step explanation:
To determine which can of pie filling costs less per ounce, we need to calculate the cost per ounce for both the pumpkin pie filling and the apple pie filling.
For the pumpkin pie filling, we divide the cost by the number of ounces:

- $2.25 / 12 ounces = $0.1875 per ounce
Comparing the two, we see that the pumpkin pie filling costs $0.18 per ounce, whereas the apple pie filling costs slightly more at $0.1875 per ounce. Therefore, the pumpkin pie filling costs less per ounce.
