Explanation:

Question 3

Step1: Recall calorie per gram of carbohydrate

Carbohydrates provide 4 calories per gram.

Step2: Calculate total calories

Multiply grams of carbohydrate (22) by 4: $22\times4 = 88$

Step1: Find protein calories

20% of 1700 - calorie diet is protein calories: $0.20\times1700 = 340$ calories from protein.

Step2: Convert protein calories to grams

Protein provides 4 calories per gram, so divide protein calories by 4: $\frac{340}{4}=85$

Answer:

88
