Question

Quizplus · Accepted Answer

To find the grams of fat in the cake, we need to convert the total kilocalories to calories and then multiply by the percentage of calories that come from fat.

1 kilocalorie = 1,000 calories

So, the total calories in the cake = 2,400 x 1,000 = 2,400,000 calories

30% of the total calories come from fat, so:

Calories from fat = 2,400,000 x 0.3 = 720,000 calories

Each gram of fat contains 9 calories, so:

Grams of fat = 720,000 / 9 = 80,000 / 1,000 = 80 grams

Therefore, the answer is (C) 80 grams.
