To determine which recipe requires the least number of berries per batch, we can calculate the pints of berries needed per batch for each recipe based on the tables provided.
For Berry Cobbler:
- 5 batches use 20 pints → 20 pints / 5 batches = 4 pints per batch
- 12 batches use 48 pints → 48 pints / 12 batches = 4 pints per batch
- 15 batches use 60 pints → 60 pints / 15 batches = 4 pints per batch
- 20 batches use 80 pints → 80 pints / 20 batches = 4 pints per batch
Average for Berry Cobbler: 4 pints per batch
For Berry Pie:
- 4 batches use 7.0 pints → 7.0 pints / 4 batches = 1.75 pints per batch
- 10 batches use 17.5 pints → 17.5 pints / 10 batches = 1.75 pints per batch
- 20 batches use 35.0 pints → 35.0 pints / 20 batches = 1.75 pints per batch
- 50 batches use 87.5 pints → 87.5 pints / 50 batches = 1.75 pints per batch
Average for Berry Pie: 1.75 pints per batch
Now, we'll compare the two recipes:
- Berry Cobbler: 4 pints per batch
- Berry Pie: 1.75 pints per batch
Therefore, Berry Pie uses less berries than Berry Cobbler.
Now, calculating how many pints less would be needed for a double batch of each recipe:
- Double batch of Berry Cobbler: 2 batches × 4 pints = 8 pints
- Double batch of Berry Pie: 2 batches × 1.75 pints = 3.5 pints
Finally, comparing the double batches:
8 pints (Berry Cobbler) - 3.5 pints (Berry Pie) = 4.5 pints less for Berry Pie.
The correct response is: Berry pie uses less berries. For a double batch, you would need 4.5 fewer pints of berries than needed for a double batch of berry cobbler.
