Answer 1

Answer:

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 = $\dfrac{45}{100}$ × 20

I.e 45% of total pizza = $\frac{45\times 20}{100}$

∴,  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
