Given the data, we can calculate the NPV for each year from 2001 to 2015. First, we need to calculate the cash inflows for each year. The cash inflows are the gross profit for each year. The gross profit is calculated as the sales minus the cost of goods sold (COGS). From the data, we know that the sales for each year are 144.72 million pounds sterling and the COGS is 87% of the sales (100% - 13% gross margin). So, the gross profit for each year is 144.72 million - 0.87 * 144.72 million = 18.81 million pounds sterling. Next, we need to calculate the present value of these cash inflows. The present value is calculated by discounting the future cash inflows at the given discount rate of 7%. The formula for calculating the present value is: PV = CF / (1 + r)^n where: - PV is the present value - CF is the cash inflow - r is the discount rate - n is the number of years So, the present value for each year from 2001 to 2015 is: PV = 18.81 million / (1 + 0.07)^n Finally, the NPV is calculated by summing up all
