Question

3. If 7 large pizzas are purchased for a party, the amount of pizza each person can have is

inversely proportional to the number of people who come to the party. If 14 people come to
the party, each person can have 6 slices. How many slices can each person have if 21 people
come to the party.

Answer 1

9 slices

Explanation:

Set up a proportion:

`(14)/(6)` =
`(21)/(x)`

Cross multiply and solve for x, the amount of slices if 21 people come:

14x = 126

x = 9

So, each person can have 9 slices
