A large hamburger (e.g., Whopper®) sandwich contains 628 kcal and 36 grams of fat.

Step-by-step explanation:

Total energy of the sandwich = 628kcal

Mass of fat contained = 36grams

Convert gram to kcal

1gram = 9kcal

36 grams = x

x = 36×9

x = 324kcal

Hence the fat contains 324kcal

%fat contained = fat(in kcal)/total calorie × 100%

%fat contained = 324/628 × 100%

%fat contained = 1/2 × 100%

%fat contained = 50%

Hence approximately 50% of the total energy is contributed by fat.

b. A data table

Step-by-step explanation:

We say that it is not a scientific model because we don't know what the table shows and because the table contains information. This information hasn't been turned into something visual, that we can call a model.
