+## ДЗ для 16 урока TMS
+
+### Average
+
+1. У нас есть
+
+```
+data class Discount(val name: String, val percent: Double, val price: Int)
+
+```
+
+2. Создать функцию, которая будет считать среднее арифметическое указанного лямбдой поля. Ниже декларация функции, нужно написать реализацию и вызов
+
+
+``` kotlin
+
+fun List.average(lambda: (T) -> Int): Int {
+ // your logic
+}
+
+```
+
+3. В тестовом методе создать список экземпляров класса Discount, который инициализовать с 10 разными Discount (поля пишите случайные)
+
+Вывести в консоль среднее значение поля price при помощи average
+
+###
