$30-33.A(typical)$ firm $in$ a perfectly competitive constant cost industry has total costs $in$ the short run given $by$:

$TC=1200+36q+3q^2,q2$

$FC=525$

$$ : AMY ZENG$|$ EASY EDU UTSC $$

where $qis$ output per day and $TCis$ the total cost per day $in$ dollars. The firm has fixed costs $of$ $$525(already$

included $in$ the $TC$ equation above$).$ The $TC$ equation generates minimum average costs $of$ $$156(per$ unit$)atq=q=20,$ with min LRAC $=$$$156,P=356-\mathrm{.}02Q$

where $Pis$ the price per unit and $Qis$ the number $of$ units demanded per day. Presently there $isno$ international
