The demand for cat treats is represented by the following equation: QD(P) = 300 – 50P, where QD represents the quantity demanded for boxes of cat treats and P represents the price of a box of cat treats in dollars. The supply of cat treats is represented by QS(P) = -100 + 50P, where QS represents the quantity supplied of cat treats and P represents the price. What is the market equilibrium price and quantity of cat treats?   I believe the best way to solve this is algebraically by solving for equation 1 and plugging in the answer from equation 1 into equation 2.
