Using the information below answer the following questions.

If demand is :Qd = 900 - 10 P and supply is: Qs = 150 + 25 P

Where: Qd = quantity of the good demanded. Qs = quantity of the good supplied. P = price of the good.

Part 1: The equilibrium price is

Part 2: The equilibrium quantity is

Part 3: An imposed price of 19.29 yields an excess demand or supply. ? of units.?

Part 4: Assuming a change in consumer preferenceshifts thedemand curve to Qd'= 630- 10 P, the new equilibrium price is

Part 5: With the newdemand in part 4, the new equilibrium quantity is
