Step 1: Calculate the equilibrium price and quantity.
The given equations are:
Demand: $Q_D = 1200 - 2P$
Supply: $P = 150 + Q_S \implies Q_S = P - 150$
At equilibrium, quantity demanded equals quantity supplied ($Q_D = Q_S$).
$$1200 - 2P = P - 150$$
$$1200 + 150 = P + 2P$$
$$1350 = 3P$$
$$P_E = \frac{1350}{3}$$
$$P_E = 450$$
Substitute $P_E =
