Question

The label on a ready-to-eat cereal box indicates that 1 cup contains 32 grams of carbohydrate, 4 grams of protein, and 2 grams of fat. how many kcal are there in two cups of this cereal?

Answer 1

Energy given by carbohydrates present in one cup =
`32 g * (4 kcal)/(1 g)` = 128 kcal

Energy given by proteins present in one cup =
`4 g * (4 kcal)/(1 g) = 16 kcal`

Energy given by fat in one cup =
`2 g * (9 kcal)/(1 g) = 18 kcal`

Total energy in one cup of cereal box = 128 kcal + 16 kcal + 18 kcal = 162 kcal

Energy present in two cups = [tex] 2 cups * \frac{162 kcal}{1 cup} *

= 324 kcal
