The amount of fat recommended for somone with a daily diet of 2000 calories is 65 g. what percent of the calories in this diet would be supplied by this amount of fat if the average number of calories for fat is 9.1 calorie/g?

29.575%

Explanation:

Data provided:

Calories taken in daily diet = 2000

Recommended amount of fat = 65 grams

Average number of calories for fat = 9.1 calories / g

Thus,

Number of calories in the diet with average number of calories for fat

= Recommended amount of fat × Average number of calories for fat

= 65 × 9.1

= 591.5 calories

Therefore,

the percentage of calories in his diet supplied = ( 591.5 / 2000 ) × 100

= 29.575%
