You are served dessert at a restaurant. You want to know what % of the calories in the dessert are from fat. The menu states tha
jasenka [17]

Answer:

39.82 %

Explanation:

Proteins and carbohydrates provide 4 calories per gram. On the other hand, fats provide 9 calories.

We can first calculate the calories of protein + carbohydrates:

       (30g + 4g) x 4 = 136 calories

And we must calculate the calories provided by fat:

        10g x 9 = 90 calories

Now to get the percentage we must see how many calories the dessert has in total:

          136 + 90 = 226 cal

This represents 100% of calories. And now we need to find out how much 90 calories are from the total.

           226 cal -----> 100%

             90 cal ------> X

       (90 x 100) / 226 = 39.82 %
