Markscheme
Award [1] for an accurate, labelled marginal revenue (MR) curve.
Examiners report
The majority of candidates were able to draw a downward-sloping MR curve with double the slope of the demand curve, intersecting the vertical axis at $300, but a common error was for the curve to intersect the horizontal axis at 40 000 (the number of tickets available) rather than 30 000.
