Consider the equations and graphs for the demand and supply functions given below, then answer the following questions. P = 3Q^2 +9Q (eq. 1) P=-2Q^2-6Ql+ 140 (eq.2) Note: P is in dollars and cents and Q is in units. Maximum Volue for Curve B Cure A Curve B (a) Explain which equations correspond with Curve A, and which one corresponds with Curve B? (b) Label the vertical and horizontal axes on the graph and identify the demand and supply functions by writing "Demand" or "Supply" inside the boxes labeled with "Curve A" or "Curve B" on the graph. (c) State the domain for these curves for the analysis to be valid. (Answer to 2 decimal places) (d) The maximum point for curve B is shown in the diagram in the left of the vertical axis. Explain why this should be the case. (e) Curve A passes through the origin. Explain why this is usually the case. (f) Calculate the equilibrium quantity and price. (Answer to 2 decimal places) Note that equilibrium occurs when the quantity demanded = quantity supplied

Trying to figure out?

mail publisher tests two for the same book." how to get rich in real state."at 15$ and 25$. He mails each to ad to 5000 rndomly selected names from a list of book buyers . 150 people order the book for 25 $, while 250 respond to the 15$ offer. The mail order publisher decides to advertise all future for 25$. Dis he make a mistake? ( hint: how much does it cost to produice and fulfill the orders for the book?
