Final answer:
The energy bar with 26g of carbohydrates and 5g of fat contains approximately 149 Calories, which rounded up is 150 Calories (option a). This is found by multiplying the grams of carbohydrates and fat by their respective caloric values and summing them up.
Step-by-step explanation:
To calculate the number of calories in the energy bar containing 26g of carbohydrates and 5g of fat, we utilize the caloric values for macronutrients: 4 Calories per gram for carbohydrates, and 9 Calories per gram for fat. Since there is no mention of protein content in this question, we will only calculate the calories from carbohydrates and fat.
The calculation is as follows:
- For carbohydrates: 26g of carbohydrates × 4 Calories/g = 104 Calories
- For fat: 5g of fat × 9 Calories/g = 45 Calories
By summing the calories from both macronutrients, we get a total energy content:
104 Calories (from carbohydrates) + 45 Calories (from fat) = 149 Calories.
Therefore, the closest answer to our calculation is 150 calories, which is option (a).
