Suppose that the demand for toy drums is described by the equation Qp = 300 - 5p, and supply is Qs = 60+ 3p, (1) What are the equilibrium price and quantity? (2) If a decrease in consumer income shifted the demand curve to Q=220-5p, how does this change affect the equilibrium price and quantity? Show the solutions using a graph and calculate the numerical answer.
