To determine the number of calories per ounce of the Greek yogurt, you can divide the total calories by the number of ounces.
Given:
- 80 calories per 5 ounces.
So, to find the calories per ounce: \[ \text{Calories per ounce} = \frac{80 \text{ calories}}{5 \text{ ounces}} = 16 \text{ calories per ounce} \]
Thus, the Greek yogurt contains 16 calories per ounce.
