To determine how much pizza sauce Julio needs to bring, we first need to figure out how many pizzas he will be making for 30 students, given that each pizza serves 8 students.
To find the total number of pizzas required: \[ \text{Total pizzas} = \frac{\text{Total students}}{\text{Pizzas per pizza}} = \frac{30}{8} = 3.75 \] Since Julio cannot make a fraction of a pizza, he will need to round up to 4 pizzas to ensure there is enough pizza for all students.
Next, we will check the pizza sauce requirements for 4 pizzas based on the provided recipe details.
According to the Pizza Sauce Recipe:
- For 1 pizza, you need 1/3 cup of sauce.
- For 2 pizzas, you would need 2/3 cup of sauce.
- For 3 pizzas, you would need 1 cup of sauce.
- For 4 pizzas, you would need 4/3 cups or approximately 1.33 cups of sauce.
Now, looking at the graph with the points given:
- Point A (3, 2) suggests 3 pizzas need 2 cups of sauce.
- Point B (4, 2.6) suggests 4 pizzas need 2.6 cups of sauce.
- Point C (4.5, 3) suggests 4.5 pizzas need 3 cups of sauce.
- Point D (6, 4) suggests 6 pizzas need 4 cups of sauce.
For 4 pizzas, the most accurate point would be point B (4, 2.6), indicating that if he is making 4 pizzas, he should prepare about 2.6 cups of sauce.
Thus, the point Julio should use to determine the amount of pizza sauce he needs to bring is: B (4, 2.6).
