Final answer:
To calculate the percentage of calories coming from 4 g of saturated fat, divide the number of calories from total fat by the total number of calories in a serving. Multiply this by the proportion of saturated fat to total fat. In this case, the percentage is 1.05%.
Step-by-step explanation:
To calculate the percentage of calories coming from 4 g of saturated fat, we need to find the proportion of calories that saturated fat contributes to the total fat. First, we calculate the percentage of total fat calories by dividing the number of calories from total fat by the total number of calories in a serving. In this case, there are 380 kcals in a serving and 22 g of total fat. So, the percentage of total fat calories is (22 g / 380 kcals) * 100 = 5.79%. Next, we calculate the percentage of calories coming from saturated fat by multiplying the percentage of total fat calories by the proportion of saturated fat to total fat. In this case, the proportion of saturated fat to total fat is (4 g / 22 g) = 0.1818. So, the percentage of calories coming from 4 g of saturated fat is 5.79% * 0.1818 = 1.05%.
