they should leave the output unchanged.
they should decrease production.
they should increase production.
they should shut down.
In a perfect competitive market P = AR = MR, as depicted by a horizontal demand curve at the given market price (R20). In the question, the
MC > MR or R25 > R20, which means firms are producing at a loss in the short run and thus need to decrease production to reach again the
profit-maximising level of output where MR = MC.

The equilibrium level of output occurs where marginal cost equals marginal revenue.
All firms are price takers.
All firms produce where average costs are minimised.
