Final answer:
The equation that best represents the situation is s = 95.
Step-by-step explanation:
The question is asking us to find the equation that represents the relationship between the number of calories in a 1-ounce serving of cheddar cheese and a 1-ounce serving of Swiss cheese. Let's assume s is the number of calories in a 1-ounce serving of Swiss cheese.
Given that a 1-ounce serving of cheddar cheese has 115 calories, which is 20 calories more than a 1-ounce serving of Swiss cheese, we can set up the equation: 115 = s + 20.
Simplifying the equation, we have s = 115 - 20, which gives us s = 95.
Therefore, the equation that represents this situation is s = 95.
