Question $3(1$ point$)$

Scenario:

You invest $$10,000$ at a nominal interest rate of $6\%$ compounded monthly for the first $10$ years, then $3\%$ compounded monthly for the next $7$ years, and $5\%$ compounded monthly for the final $8$ years?

What is the effective annual interest rate for the period of $8$ years of this investment, for which the nominal interest rate is $5\%?$

Note: when calculating interest rates, do not convert to a percent. Leave it in decimal format and round to $4$ places after the decimal. So if you think the answer is $3\mathrm{.}45678\%,$ then leave it as a proportion as $0\mathrm{.}0345678$ and then round to $0\mathrm{.}0346.$
