Perry added 88 / 2 = 44 grams of fat to the recipe. Thus, he added 44 / 4 = 11 grams of fat to each serving of food.
The answer: 11
Reverse engineering the question: Perry made a recipe that serves four people. He added a half cup of cream at the end. Cream has 88 grams of fat per cup. How many grams of fat were added to each serving of food?

Let X be the number of adults attending the concert. The number of children attending the concert is 3 * X. The theater collected a total of 7 * X + 3 * (3 * X) = $6,000. Multiplying through the parentheses we get 7X + 9X = $6,000. Adding like terms we get 16X = $6,000. Dividing both sides by 16 we get X = 375, the number of adults attending the concert. The number of children attending the concert is triple this number: 375 adults * 3 children / adult = 1125 children. The number of people attending the concert is 375 + 1125 = 1500 people.
The answer: 1500
