Answer:

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.
