Question

It is estimated that eight medium pizzas are about right to

serve a physics club meeting of 32 students. How many pizzas
would be required if the group, due to a conflicting math club
meeting, was only going to have 20 students in attendance?

Answer 1

If there are only 20 students in attendance, 5 pizzas would be required.

Step-by-step explanation:

In order to determine how many pizzas would be required if there are only 20 students in attendance, we can set up a proportion using the information given:

8 medium pizzas / 32 students = x pizzas / 20 students

To solve for x, we can cross-multiply:

8 * 20 = 32 * x

160 = 32 * x

Dividing both sides by 32, we get:

x = 160 / 32 = 5

Therefore, 5 pizzas would be required if there are only 20 students in attendance.
