Consider MechatroArm, a small manufacturer of industrial robots. At each of their manufacturing plants, they are able to produce either one, two, three, four, or five mechanic arms per day. The total revenue of a typical plant at MechatroArm is given by the following function: TR(Q)=5000+7500*Q-1000*(Q^2). And the total cost is given by: TC(Q)=2000*Q. Using marginal analysis, identify the profit-maximizing quantity for their typical plant.
