Answer:
(a) Output produced = 30 , Price = $50
Total revenue = Output produced * Price = 30 units * $50 = $1,500
Total Cost= Variable cost + Fixed cost = $1900 + 120 = $2020
At profit maximization or loss minimization point, MR = MC.
Corresponding to an output level of 30, MR=MC =$50
Note: Price is constant at $50. So, the marginal revenue will be $50 at each level of output
Profit = Total revenue - Total Cost.
Profit = $1500 - $2020
Profit = -$520.
The firm's short-run profit is -$520 if they produce using MR=MC.
(b) If a firm produces nothing, then a firm has to bear a fixed cost of $120. It means there is a loss of $120 or a profit of -$120. So, short-run profit is -$120 if they produce nothing.
(c) In the short run, if the firm produces then bear a loss of $520. if a firm produces nothing then bear a loss of $120. So, it is better to shut down the production in the short run in order to minimize the loss of the firm.
