Using our side$-$by$-$side graph methodology $($with market on the left and individual firm on the right$),$ graphically depict:

the market equilibrium price, P$0,$ and quantity, Q$0,$

the optimal output of an individual firm representative of the other firms in the industry at this LRE $($labeled as q$0),$ and

the individual firm$$s economic profit $0,$ if any $($Shade and clearly label the area representing positive or negative profits. If the profit is zero, it is not necessary to graphically depict it $$ instead, write $$$0=0$ on your graph$).$

Please include any curves necessary to identify these values. Be sure to label all relevant points, price and quantity axes, the supply and demand curves, the representative firm$$s marginal revenue, and the cost curves.$$Please use the subscript of $0($zero$)$ in labeling your curves and points $($for example, supply should be labeled as S$0).$
