To find the percentage of calories from fat in one ice cream bar, you can use the following formula:
\[ \text{Percentage of calories from fat} = \left( \frac{\text{Calories from fat}}{\text{Total calories}} \right) \times 100 \]
Substituting in the values from the label:
\[ \text{Calories from fat} = 175 \] \[ \text{Total calories} = 300 \]
Now, plug in the values:
\[ \text{Percentage of calories from fat} = \left( \frac{175}{300} \right) \times 100 \]
Calculating this gives:
\[ \text{Percentage of calories from fat} = \left( 0.5833 \right) \times 100 \approx 58.33% \]
So the percentage of calories from fat for one bar is approximately 58%.
The correct answer is 58%.
