Q. The demand curve for videos has shifted to the right. Illustrate what could have caused it?
Q. If the marketplace demand also supply functions for pizza in Newtown were
QD = 12,000 - 1,000P
QS = -4,000 + 1,000P
Find the equilibrium quantity also cost.
Starting with the demand also supplies functions from problem #1, Conclude algebraically the new equilibrium cost also quantity if
(a) the demand function changes from QD=12,000-1,000P to QD"= 8,000- 1,000,
or (b) the marketplace supply function changes from QS= -4,000 + 1,000P to QS** = 1,000P.
