is $ , an amount Rian's profit is maximized when they produce a total of phone cases. At this quantity, the marginal cost of the final phone case they produce than the price received for each phone case they sell. At this point, the marginal cost of producing one more phone case (the first phone case beyond the profit maximizing quantity) is $ , an amount than the price received for each phone case they sell. Therefore, Rian's profit-maximizing quantity occurs at the point of intersection between the curves. Because Rian is a price taker, the previous condition is equivalent to

3. Profit maximization using total cost and total revenue curves
Suppose Rian operates a handicraft pop-up retail shop that sells phone cases. Assume a perfectly competitive market structure for phone cases with a
market price equal to $20 per phone case.
The following graph shows Rian's total cost curve.
Use the blue points (circle symbol) to plot total revenue and the green points (triangle symbol) to plot profit for phone cases for quantities zero
through seven (including zero and seven) that Rian produces.
