From 2006 to 2007 stock increased by 5%

So value of stock in 2006 = 12.43 + 5% of 12.43

                                           = 12.43 + 0.6215 = $13.05

Value of stock in 2007     = 13.0515 + 5% of 13.0515

                                          = 13.0515 + 0.6525 = $13.70

In year 2008 stock increased by 10%.

so value of the stock in 2008 = 13.70 + 10% of 13.70

                                                =  13.70 + 1.37 = $15.07

The value of the stock $15.07 at the end of 2008.
