The Amalgamated Flashlight Company shows a profit of $4,500 on a production of 6000 flashlights and a profit of $10,500 when the production is 10,000

(b) Plot cost and revenue on the same axes and locate the break-even point.
(c) Suppose that the capacity of the flashlight assembly line is 30,000 flashlights. How must the price be set to make possible a $90,000 profit?
