Final answer:
To find the number of grams of carbohydrate in a product that contains 160 calories from carbohydrates, divide the number of calories by the average number of calories per gram of carbohydrates.
Step-by-step explanation:
To determine the number of grams of carbohydrate in a product that contains 160 calories from carbohydrates, we need to divide the number of calories by the average number of calories per gram of carbohydrates. The average number of calories for carbohydrates is 4.1 calories per gram. Therefore, to find the number of grams, we divide 160 by 4.1, which gives us approximately 39 grams. So, the correct answer is 40 grams.
The question asks how many grams of carbohydrate are in a product that contains 160 calories from carbohydrates. Using the given average number of calories for carbohydrates, which is 4.1 calories per gram, we can perform a simple division to find the answer. By dividing the total number of calories from carbohydrates (160) by the number of calories per gram (4.1), we get approximately 39 grams of carbohydrates.
