Question

Since beginning college, Lisa has put on about thirteen pounds. She is learning in her health science class that excess calories contribute to weight gain. One recommendation her instructor made for weight loss is to choose foods that have a low percentage of total calories coming from fat. If a 1/2-cup serving of her favorite ice cream has 310 kcal and 20 grams of fat, what percentage of total calories in the ice cream come from fat?

Answer 1

Answer: 58%

Explanation: Fat has 9 calories per gram, so if her favorite ice cream has 20g of fat the total calorie contribution from fat alone would be 180 kcal out of the 310 kcal total.

180/310

When you divide 180 by 310 you get 0.58064516 or 58%
