Questions & Step-by-Step Solutions
If a meal contains 40 grams of carbohydrates, 10 grams of protein, and 5 grams of fat, how many total calories does it provide? (Carbohydrates = 4 cal/g, Protein = 4 cal/g, Fat = 9 cal/g)
Step 1: Identify the amount of carbohydrates in the meal, which is 40 grams.
Step 2: Identify the amount of protein in the meal, which is 10 grams.
Step 3: Identify the amount of fat in the meal, which is 5 grams.
Step 4: Calculate the calories from carbohydrates by multiplying the grams of carbohydrates (40g) by the calories per gram of carbohydrates (4 cal/g). This gives you 40g * 4 cal/g = 160 calories.
Step 5: Calculate the calories from protein by multiplying the grams of protein (10g) by the calories per gram of protein (4 cal/g). This gives you 10g * 4 cal/g = 40 calories.
Step 6: Calculate the calories from fat by multiplying the grams of fat (5g) by the calories per gram of fat (9 cal/g). This gives you 5g * 9 cal/g = 45 calories.
Step 7: Add all the calories together: 160 calories (from carbohydrates) + 40 calories (from protein) + 45 calories (from fat) = 245 total calories.
