Calculate the equilibrium price and equilibrium quantity of the security.b. Suppose that the supply curve shifts to BS = 150 + 0.05b. Find the new equilibrium price and equilibrium quantity of the security.c. Explain in words, if the equilibrium price and equilibrium quantity rise or fall after the shift in supply curve.2.
