Quizplus · Accepted Answer

The profit-maximizing quantity is where marginal cost (MC) equals marginal revenue (MR). Here, MR is the market price of $8. Calculate MC for each additional 100 units: MC from 0 to 100 is $360, from 100 to 200 is $200, from 200 to 300 is $400, from 300 to 400 is $800, from 400 to 500 is $1,240, and from 500 to 600 is $1,800. The closest MC to MR of $8 is at 400 units, where MC is $8 per unit.
