If a box has 5 servings per container and the recommendation is 3 oz per serving, what is the weight of the box?

To determine the weight of the box, you multiply the number of servings by the amount of each serving. In this case, the box contains 5 servings, and each serving is recommended to be 3 ounces. Therefore, you calculate the total weight of the box as follows:

5 servings × 3 ounces per serving = 15 ounces.

This means the correct answer is 15 ounces, reflecting the total weight that the box would provide based on the serving size recommendation.
