Answer:
The quantity of customers is 4000, and the price is $30.
Explanation:
Assumed that the table is provided depicting the pricing and revenue structure.
Now, that the profit is maximized for monopoly when the Marginal Revenue = Marginal Cost.
That is when additional cost is recovered from additional revenue.
Here, when 4,000 customers are their then Marginal Revenue for each 1,000 customers = $30,000
Thus, marginal revenue for each customer = $30,000/1,000 = $30 for each customer.
And since the marginal cost is also $30 for each customer:
Maximum profit shall be:
MC $30 = MR $30
