If the literature supplied by the fast-food chain indicates that one hot apple pie contains 2 g of protein, 14 g of fat, and 31 g of carbohydrates, how many calories are contained in one hot apple pie?

Rationale: Calories are calculated as: (2 g protein × 4 kcal/g) + (14 g fat × 9 kcal/g) + (31 g carbohydrates × 4 kcal/g) = 8 + 126 + 124 = 258 kcal, closest to 270 kcal.
