The following time series data represent the yearly amounts spent on advertising (in millions of dollars) by a large toy company:

23.3, 21.7, 22.7, 25.5, 22.7, 25.9

This series of data begins in year 1997(i.e., time period t=1 corresponds to 1997). Using regression analysis, a linear trend line of the form Tt=21.77 + 0.53t was fit to the data. Using this information, generate a forecast for the total yearly amount of money that will be spent on advertising in 2006.
