Question

A meal consisting of a cheeseburger, large fries, and a chocolate shake provides a total of 1,120 kilocalories. forty-eight percent of the energy in the meal is from carbohydrate and 13 percent is from protein. how many kilocalories of fat does the meal contain?

Answer 1

For this case, we have that the remaining percentage of food belongs to fats.
 We have then that the percentage that belongs to fats is:
 100 - 48 - 13 = 39%
 Then, the amount of kilocalories from fats is:
 (0.39) * (1120) = 436.8
 Answer:
 the meal has 436.8 kilocalories of fat
