Question
  1. Consider the following general linear demand and supply functions that represent a market:

 

Qd = Z −GP                                                                                                 (3)

Qs = D + EP+ CS                                                                                           (4)

where P is the price, S is a variable denoting the average amount of production shipping costs, and Qd and Qs

are the quantity demanded and the quantity supplied. Assume D, E, G, and Z all have values greater than zero.
