Final answer:
To make 5 batches of strawberry shortcake, you will need 12 pounds of cake and 3.75 pounds of strawberries.
Step-by-step explanation:
To calculate the total amount of cake and strawberries needed for 5 batches of strawberry shortcake, we need to multiply the amount needed for one batch by 5. Each batch requires (12/5) pounds of cake and (3/4) pound of strawberries.
The total amount of cake needed for 5 batches is (12/5) * 5 = 12 pounds. The total amount of strawberries needed is (3/4) * 5 = 3.75 pounds.
