At an output level of 3, the firm will earn a maximum profit because marginal cost went below the marginal revenue to being above MR at a quantity of four. And, it is passing by MR at the output level of 3.

MR is $15/unit. And, after 3 units the MC starts increasing more than MR, therefore, 3 units are the profit maximization level of output.
