One slice of bread contains 18 g carbohydrates, 4 g protein, and 1.5 g fat. \approx imately how many kcal are in two slices? a. 48. b. 94. c. 101. d. 203.

The number of calories in a food is calculated by multiplying the number of grams of each macronutrient by the caloric value of that macronutrient, and then adding up the results. The caloric value of carbohydrates, protein, and fat are 4, 4, and 9 kcal/gram, respectively. So, for one slice of bread: - Carbohydrates: 18 g x 4 kcal/g = 72 kcal - Protein: 4 g x 4 kcal/g = 16 kcal - Fat: 1.5 g x 9 kcal/g = 13.5 kcal Total: 72 + 16 + 13.5 = 101.5 kcal For two slices of bread, we just double everything: - Carbohydrates: 2 x 18 g x 4 kcal/g = 144 kcal - Protein: 2 x 4 g x 4 kcal/g = 32 kcal - Fat: 2 x 1.5 g x 9 kcal/g = 27 kcal Total: 144 + 32 + 27 = 203 kcal Therefore, the correct answer is d. 203.
