Quizplus · Accepted Answer

To find the number of grams of fat in the cake, we need to first find the total number of kilocalories from fat. We can do this by multiplying the total number of kilocalories (2,400) by the percentage of calories that come from fat (30% or 0.3):

2,400 x 0.3 = 720 kilocalories from fat

Next, we need to convert kilocalories to grams, since the nutrition labels on food typically list fat in grams. One gram of fat has 9 kilocalories, so we can divide 720 by 9 to get the number of grams of fat:

720/9 = 80 grams

Therefore, there are 80 grams of fat in the pound cake. The correct answer is C, 80 grams.
