Suppose the supply of a good is given by the equation Qs = -10 + 2P and the initial demand for the good is given by the equation Qd = 70 - 2P, where quantity (Q) is measured in thousands of units and price (P) is measured in dollars per unit. Now suppose a change in consumer tastes results in a new demand curve given by Qd = 50 - 2P Seject one: a. Equilibrium price increases by $5 b. Equilibrium quantity increases by 10 thousand units C. The initial equilibrium quantity is 20 thousand units O d. The new equilibrium price is $15
