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.

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

Step-by-step 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 = × 20

I.e 45% of total pizza =

∴,  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
