Interpretation:
The percentage of total calories obtained from fat is to be calculated.
Concept Introduction:
Fats and oils are composed of organic molecules called triglycerides. Triglycerides are the main sources of fats in the body.
Polyhydroxy

Answer to Problem 61E
Solution:
a)
b)
c)
Explanation of Solution
a) In Little Debbie choco-cakes,
Fats have a high calorific value, that is, up to
The number of calories in each product can be calculated as follows:
Thus, the total number of calories obtained is
The percentage of fatscan be calculated as follows:
Substitute
Therefore, the percentage of calories obtained from fats is
