Given a downward-sloping demand curve and an upward-sloping supply curve for product A, an increase in the price of complementary product B and the decrease in the price of a resource used in making product A will increase equilibrium quantity, but the change in equilibrium price will depend on the relative sizes of the shifts in demand and supply. O decrease equilibrium quantity, but the change in equilibrium price will depend on the relative sizes of the shifts in demand and supply. O increase equilibrium price, but the change in equilibrium quantity will depend on the relative sizes of the shifts in demand and supply. O decrease equilibrium price, but the change in equilibrium quantity will depend on the relative sizes of the shifts in demand and supply. keep equilibrium price and quantity the same
