A graph showing demand ( ) and marginal revenue ( ), average total cost ( ), average variable cost ( ), and short-run marginal cost ( ), with quantity of output ( ) on the horizontal axis and revenue and costs in dollars on the vertical axis. and both have vertical intercepts of $40; has horizontal intercept at 400 units and has horizontal intercept at 800 units. At =150 , =$5 , ==$24 , =$33 , and =$35 . At =300 , ==$10 , =$20 , =$25 , and =$30 . At =450 , is negative, , , and all intersect at $17, and =$26 . At =550 , is negative, =$13 , =$17 , and = at $26. If the firm decided to produce 200 units of output, what would be the marginal revenue and the price
