Question

To celebrate ratios, Mrs. Johnson’s class will make pizzas. Julio is in charge of bringing in the sauce. There are 30 students in his class and each pizza serves 8.

Answer 1

B

Explanation:

One pizza serves 8 students. How many pizzas are needed for 30 students?

1 pizza - 8 students

x pizzas - 30 students

8x = 30

x = 30/8

x = 3.75

We need to round up, so we need 4 pizzas.

How many cups for 4 pizzas?

For 1 pizza, we need 2/3 cups.

So

For 2 pizzas, 2*(2/3) = 4/3 cups

For 3 pizzas, 3*(2/3) = 2 cups

For 4 pizzas, 4*(2/3) = 8/3 cups

The point that represents (4, 8/3) is point B, which is the answer of the question.
