Suppose that a survey statistical analysis of the average wage $x$ in a certain region and the average consumption $y$ in that region reveals a correlated relationship between $y$ and $x$. The regression line equation is given by $\hat{y} = 0.7x + 2.1$ (in units of thousands of yuan). If the average consumption level in this region is 10.5, then the estimated percentage of average consumption expenditure to average wage income in this region is $\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_.$
