Ethan had 7 of his friends over. He ordered cheese pizzas and mozzarella sticks for the 8 of them. In all, there were 64 pieces of food. If each person had 5 slices of pizza, find the number of mozzarella sticks each person ate (1 point)
Each person ato mozzarella sticks.
Since each person had 5 slices of pizza and there were 8 people, the total number of pizza slices is 5 slices/person * 8 people = <<5*8=40>>40 slices of pizza.
If there were 64 food pieces in total and 40 of them were pizza slices, the remaining 64 - 40 = <<64-40=24>>24 food pieces were mozzarella sticks.
Since each person had mozzarella sticks, each person ate 24 mozzarella sticks / 8 people = <<24/8=3>>3 mozzarella sticks/person. Answer: \boxed{3}.
