Question 5

The label on a bag of potato chips indicates that one serving contains 250 Calories, with 150 Calories from fat. What percent of Calories comes from fat?

Accepted Answer

To find the percent of Calories that come from fat, we need to calculate the fraction of Calories from fat and then convert to a percentage. We have:

Fraction of Calories from fat = Calories from fat / Total Calories 
Fraction of Calories from fat = 150 / 250 
Fraction of Calories from fat = 0.6

To convert the fraction to a percentage, we multiply by 100:

Percent of Calories from fat = 0.6 * 100 
Percent of Calories from fat = 60

Therefore, the answer is choice letter C, 60%.
