Award marks as follows:
- [1 mark] for each appropriately labelled axis (the vertical axis must include reference to both costs and revenue) - award a maximum of [2 marks].
- [1 mark] for an accurately drawn and labelled total revenue curve.
- [1 mark] for an accurately drawn and labelled total costs curve.
- [1 mark] for the identification of the break-even level of output.
N.B. If candidates use the word "sales" instead of "revenue" accept. In many places in the world, sales and revenue are virtually synonyms, at least in everyday use.
Award [0 marks] if a candidate produces a table, and award no more than [3 marks] if the chart is not neat, not drawn with a straight-edge, or is not to scale. If a candidate produces a chart with no figures (which prevents determination if it is to scale) but in other respects it is fully accurate, award a maximum of [3 marks].
Ideally, the candidate will draw an arrow pointing to the break-even point and label the arrow. However, accept as an "accurately labelled" break-even point, a vertical line from the x-axis to the break-even point provided that the line is labelled "break-even point".
