Question: The Baker Company manufactures and sells a line of sewing machines. Demand per period (Q) for a particular model is given by the following relationship:

Q = 400 – .5P

where P is price. Total costs (including a "normal" return to the owners) of producing Q units per period are:

TC = 20,000 + 50Q + 3Q²

(a)	Express total profits (?) in terms of Q. (equation format).
(b)	At what level of output are total profits maximized? What price will be charged? What are total profits at this output level?
