Relative Growth Rate, Using Derivatives

In 1910 the actual real GDP was at 1,270 and increased to 14,000 by the end of 2010. If the GDP is modeled by $y = Ce^{kt}$, where $t$ is time, $C$ is the initial GDP in 1910, and $k$ is the relative growth rate, find $k$ as a percent rounded to the nearest tenth.
