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 ate mozzarella sticks
Since each person ate 5 slices of pizza and there were 8 people, the total number of pizza slices eaten is 5*8 = <<5*8=40>>40 slices.
If there were 64 pieces of food in total and 40 of them were pizza slices, then the number of mozzarella sticks eaten is 64 - 40 = <<64-40=24>>24 pieces.
Since there were 8 people, each person ate 24/8 = <<24/8=3>>3 mozzarella sticks. Answer: \boxed{3}.
