The table above shows some of the costs for a perfectly competitive firm. The firm will produce 9 units of output if the price per unit is
A) $1750.
B) $200.
C) $300.
D) $500.
 
the costs for a perfectly competitive firm produces at MC=P
MC of n the unit=(VC of n units -VC of p units
)/(n-p)...............n>p
MC(9)=(1000-800)/(9-8)
=200 units
the price should be equal to $200
option B
