Payday loans are very short$-$term loans that charge very high interest rates. You can borrow $$300$ today and repay $$363$ in two weeks.

What is the compounded annual rate implied by this $21$ percent rate charged for only two weeks? $($Hint: Compound the $2-$week return $26$ times for the annual return.$)$

Note: Do not round intermediate calculations and round your final answer to $2$ decimal places.
