Let's break down the problem step by step.
- Total number of people: Ethan + 7 friends = 8 people.
- Total pieces of food: 64 pieces.
- Slices of pizza each person had: 5 slices.
Total slices of pizza consumed: \[ 8 \text{ people} \times 5 \text{ slices/person} = 40 \text{ slices of pizza} \]
Now we can find the number of mozzarella sticks by subtracting the number of slices of pizza from the total pieces of food: \[ \text{Number of mozzarella sticks} = \text{Total pieces of food} - \text{Total slices of pizza} = 64 - 40 = 24 \text{ mozzarella sticks} \]
Now, we divide the total mozzarella sticks by the number of people to find out how many each person ate: \[ \text{Mozzarella sticks per person} = \frac{24 \text{ mozzarella sticks}}{8 \text{ people}} = 3 \text{ mozzarella sticks/person} \]
So, each person ate 3 mozzarella sticks.
