Mary Jones has been given the job of finding the best way to present the company’s advertising expenses at a forthcoming meeting. She has obtained the data in Table 2.15.

Mary has access to a computer and Excel software. She has examined the various options offered by ChartWizard such as pie-charts, doughnuts, columns, and bar charts. Mary has decided on two options: (i) two three-dimensional pie charts, one for each year (ii) a line chart with the two sets of figures on the same chart. You are asked to help Mary create the charts and then choose between the two presentations, giving reasons for your choice.
