1)Following the nutritional label on a jar of peanut butter, you determine that 1 ounce of the peanut butter contains 115 calories and 9 grams of fat. What percent of the calories come from fat.
a)30
b)40
c)70
d)80
i put c
Divide 9 by 115 and multiply by 100.
The answer is not c.
There are 9 calories in a gram of fat. 9x9=81 calories. 81/115=70.4%. C is the correct answer
To determine the percentage of calories that come from fat in the peanut butter, you need to calculate the total number of calories that come from fat and then divide it by the total number of calories in 1 ounce.
Given that 1 ounce of peanut butter contains 115 calories and 9 grams of fat, you need to convert the grams of fat to calories because fat contains 9 calories per gram.
So, 9 grams of fat x 9 calories per gram = 81 calories from fat.
To find the percentage, you divide the calories from fat (81) by the total calories (115) and multiply by 100:
(81 calories / 115 calories) x 100 = 70.43%
Therefore, 70.43% of the calories in 1 ounce of peanut butter come from fat.
Option c) 70 is the correct answer.
