Question

how many grams of carbohydrate are in a meal that is 50% carbohydrates and contains 600 calories? select one: a 90 b 75 c 150 d 300

Explanation:

Step1: Find calorie from carbs

The meal is 50% carbs, so carb calories = \( 600 \times 0.5 = 300 \) calories.

Step2: Convert calories to grams

Carbohydrates provide 4 calories per gram. So grams of carbs = \( \frac{300}{4} = 75 \)? Wait, no—wait, maybe I messed up. Wait, no, wait: Wait, the problem—wait, maybe the standard is 4 calories per gram for carbs. Wait, but let's re - check. Wait, the meal has 600 total calories, 50% from carbs. So carb calories: \( 600\times0.5 = 300 \) calories. Then, since 1 gram of carb has 4 calories, grams of carb = \( 300\div4 = 75 \)? But wait, the options—wait, no, maybe I made a mistake. Wait, no, wait, maybe the question is different. Wait, no, the problem says "how many grams of carbohydrate are in a meal that is 50% carbohydrates and contains 600 calories?" Wait, no, maybe the 50% is of the grams? No, no, calories from carbs. Wait, 1 gram of carbohydrate = 4 calories. So if the meal has 600 calories, 50% from carbs: 300 calories from carbs. Then grams of carbs = 300 / 4 = 75? But the options have B as 75. Wait, but let's do it again.

Wait, total calories = 600. Percentage of calories from carbs = 50%. So calories from carbs = 0.5 * 600 = 300 calories. Since 1 gram of carbohydrate provides 4 calories, the number of grams of carbohydrate = 300 / 4 = 75 grams. So the answer should be 75, which is option B.

Answer:

B. 75
