Quizplus · Accepted Answer

To calculate the percentage of calories from fat, we need to know the total number of calories in the slice of pumpkin bread. We can use the following equation to calculate the total number of calories in the slice of bread:

Total calories = (Number of grams of fat x 9) + (Number of grams of carbohydrate x 4) + (Number of grams of protein x 4)

Plugging in the values, we get:

Total calories = (5 x 9) + (40 x 4) + (5 x 4)
Total calories = 45 + 160 + 20
Total calories = 225

Now we can calculate the percentage of calories from fat:

Percentage of calories from fat = (Number of grams of fat x 9) / Total calories x 100%

Plugging in the values, we get:

Percentage of calories from fat = (5 x 9) / 225 x 100%
Percentage of calories from fat = 45 / 225 x 100%
Percentage of calories from fat = 20%

Therefore, the correct answer is B) 20%.
