Answer 2

Answer:

The answer to your question is "it is necessary to order 85 pizzas to feed 300 students"

Step-by-step explanation:

Data

7 pizzas feed 25 students

? pizzas feed 300 students

To solve this problem use proportions

We know:

                          7 pizzas ------------------   25 students

                           x pizzas -----------------   300 students

Solve using cross multiplication

                           x = (300 x 7) / 25

Simplification

                           x = 2100 / 25

Result

                           x = 85 pizzas
