Suppose Jayden 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 Jayden's total cost curve. Use the blue points (circle symbol) to plot totak revencie and the gneen points (criangle symbol) co plot proft for phone cases for quantities zero through seven (including zero and seven) that Jayden produces. Calculate Jyden's marginal revonue and marginal cost for the first seven phone cases they produce, and plot them on the following graph. Use the blue points (cirde symbol) to alot marginal revenue and the orange points (square symbol) to plot marginal cast at each quantity. Jayden's profit is maximized when they produce a total of phone cases. At this quantity, the marginal cost of that final phone case they Droduce is an amount than the price recelved for each phone case they sell. At this point, the maroinal cost of producing one more phone case (the first phone case beyond the profit maximizing quantity) is in amount than the price received for each phone case they sell. Therefore, layden's profit-maximizing quantity occurs at the point of intersection between the curves. Because layden is a price taker, the previous condition is equivalent to
