To determine how many calories are in 1 ounce of soda, follow these steps:
1. Identify the total calories and the total volume: We know there are 104 calories in an 8-ounce serving of soda.
2. Set up the relationship: This means that 104 calories are distributed evenly across 8 ounces.
3. Calculate the calories per ounce: To find out how many calories are in just 1 ounce, divide the total calories by the total number of ounces.
[tex]\[
\text{Calories per ounce} = \frac{\text{Total calories}}{\text{Total ounces}} = \frac{104 \text{ calories}}{8 \text{ ounces}}
\][/tex]
4. Perform the division: When you divide 104 by 8, you get 13.
Thus, there are 13.0 calories in 1 ounce of soda.
