Answer: You would be consuming 250 calories.
Step-by-step explanation: The serving size of the hamburger with cheese is given as 316 grams and that contains 790 C of energy.
From this information we can deduce the calorie content per gram as follows;
C per Gram = 790/316
C per Gram = 2.5
So from our calculations, for every gram consumed, you take in 2.5 C.
Therefore, for someone that consumes 100 Grams, the Calorie intake would be derived as follows;
Total C = Total grams x C per Gram
Total C = 100 x 2.5
Total C = 250
Therefore for a 100 gram hamburger, you would be consuming 250 calories.
