Answer:
Loss, shutdown
This firm is making a loss and should shutdown
Step-by-step explanation:
For a firm to be make a profit the maximization rule need to be considered, This maximization rule simply states that if a firm opts for maximizing its profits, it definitely has to choose such a level of output where Marginal Cost (MC) is equal to Marginal Revenue (MR). And Marginal Cost should be rising, we can also say, MR=MC.
In this case where 500 batteries a month is the output level at which MR = MC.
Where marginal revenue suppose to be 500 x 105 = 52,500 but instead it is equal to marginal cost which is 10,000.
This simply implies that this firm is making a loss and should shutdown
