Consider a market where the quantity demanded is represented by the function $Q_d = 150 - 3P$ and the quantity supplied is represented by the function $Q_s = -30 + 6P$. What are the equilibrium price (P*) and equilibrium quantity (Q*) in this market?

Equilibrium Calculation Review

A student is analyzing a market where the quantity demanded is given by the function $Q_d = 100 - 2P$ and the quantity supplied is given by $Q_s = 10 + P$. The student concludes that the market reaches equilibrium at a price of $30 and a quantity of 70. Is the student's conclusion correct?

Calculating Equilibrium with a Per-Unit Tax

Arrange the following steps in the correct logical sequence to algebraically determine the equilibrium price and quantity from a market's direct demand and supply functions.

Justification of the Equilibrium Condition

For each market described by a pair of demand and supply functions, match it with the correct equilibrium price (P*) and quantity (Q*).
