3 ounces of blackberries
2 ounces of raspberries
0 ounces of strawberries
================================================
Step-by-step explanation:
The pie needs
- 9 oz of blackberries
- 10 oz of raspberries
- 12 oz of strawberries
Each container at the store is 12 oz of berries
After making 1 pie, he'll be left with...
- 12-9 = 3 oz of blackberries
- 12-10 = 2 oz of raspberries
- 12-12 = 0 oz of strawberries
That makes 3+2+0 = 5 ounces of berries total
