2. Let P represent the price of apples; let Q D represent the quantity of apples demanded; and let Q 5 represent the quantity of apples supplied. The demand for apples is given by the equation, QD = 600 1.5P. The supply of apples is given by the equation, 05 = 40 + 2.5P. a. Solve the equilibrium price and quantity in the market. b. If the cost of producing every unit of apples increases by 8, how do the equilibrium price and quantity change
