Answer:
To calculate the energy consumed by the client, we need to use the following formula:
Energy (in calories) = (grams of carbohydrate x 4) + (grams of protein x 4) + (grams of fat x 9)
First, let's calculate the amount of each nutrient in the 180ml serving:
Carbohydrates: (75 ml / serving) x (13.5 g / 75 ml) x 180 ml = 32.4 g
Protein: (75 ml / serving) x (10 g / 75 ml) x 180 ml = 24 g
Fat: (75 ml / serving) x (4 g / 75 ml) x 180 ml = 9.6 g
Now we can calculate the energy consumed:
Energy = (32.4 g x 4) + (24 g x 4) + (9.6 g x 9) = 129.6 + 96 + 86.4 = 312 calories
Therefore, the client has consumed 312 calories from the 180 ml serving of the product.
