How many boxes of boxed scalloped potatoes needed to feed 90 people?

To determine the number of boxes of boxed scalloped potatoes needed to feed 90 people, we need to consider the serving size of each box. Let's assume that each box of boxed scalloped potatoes serves 4 people.

To calculate the number of boxes needed, we can use the formula:

Number of boxes = (Total number of people) / (Serving size of each box)

In this case, we have:

Number of boxes = 90 people / 4 servings per box

Number of boxes = 22.5

Since we can't buy half a box, we would need to purchase 23 boxes of scalloped potatoes to ensure that there is enough food for 90 people.
