2.XYZ Plc is considering extending its opening hours. It commissioned a market research study for 1,000(sunk cost) to assess the likely impact on customer demand. The study concluded that there would be a 5% increase in business from additional sales during the extended opening hours, yielding an annual gross profit of 23,000. However, 25% of these additional sales would simply have moved from the existing opening hours. The staff costs associated with the additional opening hours would be 5,000 per annum. A review of other overheads (82,000 per annum) indicates that 90% of these costs are fixed, while the balance varies with sales. Based on this information what would be the incremental annual profit (or loss) arising from extending the opening hours?
