We will have the following:
Using exponential regression we will have that the line of best fit will be:
![f\mleft(x\mright)=8585.658603*1.399211892^x](https://img.qammunity.org/2023/formulas/mathematics/college/oodawmwvz3k5p36x5sud4odsyl72z2xi5o.png)
Now, we will have that:
![\begin{gathered} 300000=8585.658603*1.399211892^x\Rightarrow34.94199034=1.399211892^x \\ \\ \Rightarrow x=(ln(34.94199034))/(1.399211892)\Rightarrow x= \end{gathered}](https://img.qammunity.org/2023/formulas/mathematics/college/lbfobt1corvmt2yuo0sauzs3maoe6wkq47.png)
So, the approximation using linear regression gives us as solution approximately 29.7 years; thus the closest one to match is then
