Фирма, находясь в условиях совершенной конкуренции, имеет функцию общих затрат ТС=140+10Q+40Q2. При каком выпуске прибыль фирмы будет максимальна, если цена установилась на уровне 250 ден. ед.? Определить размер прибыли фирмы.
MR (прибыль)=TR(общая выручка)-TC(общие издержки)=P*Q-TC=P*Q-140-10Q-40Q^2=250Q-140-10Q-40Q^2=-140+240Q-40Q^2→max
Q=3 – точка максимума (определяется при подстановке в производную значений меньших и больших трех, при прохождение с + на – получается точка максимума)
