Question

A caterer prepares three times as many pizzas as she usually prepares for a large party.

The caterer usually prepares 5 pizzas. The caterer also estimates that each party guest will eat 1/3 of a pizza. Write an expression that represents this situation. How many party guests will the pizzas serve?

Answer 1

3 x 5 pizzas = 15 pizzas
1/3 of pizzas x people = 15 pizzas
people = 15 pizzas / (1/3) = 45

Answer 2

Answer: There are 45 party guests who will be served pizzas.

Explanation:

Since we have given that

Number of pizzas usually prepare by the caterer = 5

Part of pizza will eat by each party guest is given by

`(1)/(3)`

As we have given that a caterer prepares 3 times as many pizzas as she usually prepares for a large party,

So, it becomes

`\text{Number of pizzas prepare by carterer this time}=5* 3=15\\`

Let the number of party guests be x

According to question, it becomes,

Number of party guests will get the pizza serve is given by

`(1)/(3)* x=15\\\\x=15* 3\\\\x=45`

Hence, there are 45 party guests who will be served pizzas.
