Final answer:
Everett will need 7.5 cups of sherbet to make 3 bowls of punch, as he uses 2.5 cups for one bowl.
Step-by-step explanation:
To calculate the amount of sherbet Everett needs to make 3 bowls of punch, we multiply the amount of sherbet needed for one bowl by the number of bowls he wants to make. Everett uses 2.5 cups of sherbet for one bowl of punch.
Therefore, for 3 bowls, he will need:
2.5 cups/bowl × 3 bowls = 7.5 cups of sherbet.
This is a basic arithmetic multiplication problem, which is commonly encountered in real-world cooking measurements and recipes.
