I'd choose c

Answer:

d. 582 kilocalories

Explanation:

To know how many calories Jane ate for breakfast, we need to make a very simple calculation. But before calculating, we should know that 1 gram carbohydrate contains 4 calories, 1 gram protein contains 4 calories and 1 gram contains 9 calories.

Knowing this, we simply multiply and add as follows:

 (85x4 = 340) + (20x4 = 80) + (18x9 = 162) = 340 + 80 + 162 = 582 kilocalories.
