To find the total number of calories in one serving of sweet potato chips, we can set up a mathematical equation based on the information given.
Let \( x \) represent the total number of calories in one serving of sweet potato chips. According to the information provided, the calories from fat (12.6 calories) represent 9% of the total calories.
This can be expressed with the equation:
\[ 0.09x = 12.6 \]
Now, you can solve this equation to find \( x \), which represents the total number of calories in one serving of sweet potato chips.
To solve for \( x \):
\[ x = \frac{12.6}{0.09} \]
You can then calculate the value of \( x \).
