The question is-

If you can earn 25,000 a year today and the inflation rate continues at 3% per year, you'll need to make $33,598 in 10 years to have the same buying power. You would need to make $44, 771 if the inflation rate jumped to 6%. Confirm that these statements are accurate by finding the geometric mean rate of increase.

How do I set these up to solve and what are the correct answers?

Thanks!

(\frac{33598}{10000})^{\frac{1}{10}}


25000(1+\frac{3}{100})^{\10}=33598

25000(1+\frac{6}{100})^{10}=44771
