Question
Suppose products A and B have demand and supply equations that are related to each other. If qд and qB are the quantities produced and sold of A and B, respectively, and PA and PB are their respective prices, the table below shows the demand equations and the supply
equations. Eliminate qд and qB to get the equilibrium prices.
demand equations
9A 3-PA PB
supply equations
9A = -7 +6PA - 2PB
9B = 22+ PA - PB
9B = -3-2PA +бPB
The prices are PA S
and PB = $
(Round to the nearest cent as needed.)
