Where the above graph is given, the price at which profit will be maximized is at $8 dollars.
This is because in a monopolistically competitive market, the profit is maximized at the point where Marginal Revenue (MR) is equal to Marginal Cost.
Monopolistic competition is a form of imperfect competition in which several manufacturers compete with one another, but their products are unique and hence cannot be perfectly substituted.
The monopoly will choose to produce at the quantity where marginal revenue equals marginal cost, or MR = MC, in order to maximize profits.
When a monopoly produces less, MR > MC at certain production levels, allowing the business to increase profits through output expansion.
