Final answer:
To find the percent of calories that come from fat, divide the total calories from fat by the total calories and multiply by 100. In this case, it is 31.30%.
Step-by-step explanation:
To find the percent of calories that come from fat, we need to determine the number of calories from fat and divide it by the total number of calories.
Given that there are 12 grams of fat per serving and 9 calories per gram of fat, the total number of calories from fat is 12 * 9 = 108 calories.
Since the total number of calories per serving is 345, the percent of calories that come from fat is (108 / 345) * 100 = 31.30%
