Объяснение:

Мы можем сразу воспользоваться формулой точечной эластичности спроса по цене для непрерывного случая, так как нам известна функция спроса по цене: (1) Edp = Q'p*P0/Q0

Для формулы нам потребуется найти производную функции Qd(P) по параметру P: Q'p = (100 - 2P)'p = -2. Обратите внимание на отрицательный знак производной. Если закон спроса выполняется, то производная функции спроса по цене всегда должна быть отрицательной.

Теперь найдем вторую координату нашей точки: Q0(P0) = Q0(10) = 100 - 2*10 = 80

Подставляем полученные данные в формулу (1) и получаем ответ: Edp = -2 * 10/80 = -0, 25
