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