Question

Juan ordered 20 pizzas for a party. 45% of the pizzas has 8 slices each. The remaining 55% of the pizzas have 12 slices each. Complete the model. Then complete the statement to fine the total number of slices of pizza.

Answer 1

The total number of slices of pizza in 20 pizzas is 204 .

Explanation:

Given as :

The total number of pizza ordered = 20 pizza

The number of slices for 45% of total pizza = 8

The number of slices for 55% of total pizza = 12

Let the total number of slices of pizza = n

Now, According to question

45% of total pizza =
`(45)/(100)` × 20

I.e 45% of total pizza =
`(45* 20)/(100)`

∴, 45% of total pizza = 9

Again

55% of total pizza = Total pizza - 45% of total pizza

Or, 55% of total pizza = 20 - 9

∴ 55% of total pizza = 11

Now,

The total number of slices of pizza = 45% of total pizza × The number of slices for 45% of total pizza + 55% of total pizza × The number of slices for 55% of total pizza

i.e n = 9 × 8 + 11 × 12

or, n = 72 + 132

∴ n = 204

So, The total number of slices of pizza = n = 204

Hence,The total number of slices of pizza in 20 pizzas is 204 . Answer
