a.) 450
b.) there is no way to calculate the calories from this information.
c.) 120
d.) 270

Explanation:

Step1: Recall calorie values per nutrient

Fat provides 9 calories per gram, carbohydrates provide 4 calories per gram, and protein provides 4 calories per gram.

Step2: Calculate calories from fat

Calories from fat = $30 \text{ g} \times 9 \text{ cal/g} = 270$ calories.

Step3: Calculate calories from carbohydrates

Calories from carbohydrates = $30 \text{ g} \times 4 \text{ cal/g} = 120$ calories.

Step4: Calculate calories from protein

Calories from protein = $15 \text{ g} \times 4 \text{ cal/g} = 60$ calories.

Step5: Sum up all calories

Total calories = $270 + 120 + 60 = 450$ calories.

Answer:

a.) 450
