To calculate the percentage of total kilocalories due to fat, we need to first calculate the total number of kilocalories in the cheeseburger. We know that the burger contains 640 kcal, so we can set up the following equation:

640 kcal = X kcal from fat + Y kcal from other sources

We know that the fat in the burger contains 39 g of fat, and that fat contains 9 kcal per gram, so we can calculate the number of kcal from fat:

39 g x 9 kcal/g = 351 kcal from fat

Now we can substitute this value into the equation above:

640 kcal = 351 kcal from fat + Y kcal from other sources

Solving for Y, we get:

Y = 640 kcal - 351 kcal = 289 kcal

So the burger contains 351 kcal from fat and 289 kcal from other sources. To calculate the percentage of total kilocalories due to fat, we divide the number of kcal from fat by the total number of kcal and multiply by 100:

(351 kcal / 640 kcal) x 100 = 54.8%

So, the percentage of total kilocalories due to fat in the double cheeseburger with bacon is 55%, which corresponds to choice D.
