Question 5 [12] Explain with the aid of a relevant diagram (you have to draw the diagram) how profit is maximised when marginal revenue equals marginal cost.

(6) Briefly discuss the diagram to illustrate your understanding of the concept (and diagram). (6) Tip: You have to draw a diagram that shows the MC and AC curves, as well as the MR and AR curves. Price and quantity changes must clearly be indicated on the diagram. Interpret the diagram and discuss it to show your understanding
