HL exam practice: Linear equilibrium
A local Australian renewable-energy market report gives demand as \(Q_d = 132 - 3P\) and supply as \(Q_s = 27 + 7P\). Explain how HL students should find the equilibrium price and why this is an equilibrium. Use the diagram labels, numerical evidence, and policy context before writing the final judgement. Enter the answer and choose the interpretation that best matches the HL economic evidence.
Worked practice: economic evidence and answer
Identify the economic evidence first, then state the result and interpretation.
Write a full answer
Now write the response in full, in your own words — this is what the exam asks for. The AI marks it on the same moves you built above (focus, evidence, technique, judgement) and gives feedback on reasoning, evidence, and expression.
