Question

One gram of sugar has 4 calories. A can of chili with beans has 10 grams of sugar. There are 540 calories in the can. What percent of the calories in the can is from sugar? Round to the nearest whole percent.

a) 2%
b) 6%
c) 9%
d) 19%

Answer 1

To calculate the percentage of calories from sugar in a can of chili, multiply the amount of sugar by the calories per gram of sugar, divide by total calories, and multiply by 100 to get the percentage. The result is approximately 7%, which is closest to option c) 9%.

Step-by-step explanation:

To find the percentage of calories from sugar in the can of chili, we need to calculate the total calories from sugar and then find what percentage that is of the total calories in the can.

• First, we multiply the amount of sugar in the can by the number of calories per gram of sugar: 10 grams of sugar x 4 calories per gram = 40 calories from sugar.
• Next, we take the total calories from sugar and divide it by the total calories in the can to get the fraction of calories from sugar: 40 calories from sugar / 540 total calories = 0.0741.
• Finally, we convert the fraction to a percentage by multiplying it by 100: 0.0741 x 100 = 7.41%, which we round to the nearest whole percent to get 7%.

Therefore, the percentage of calories from sugar in the can is approximately 7%. This means the correct answer is not listed in the options provided, as it would have been closest to option c) 9%.
