## Problem

Bob Bluster, the KNEWS meteorologist, determined that the mathematical odds of $\emph{no rain}$ tomorrow are 11:9. What would a mathematics student determine as the percent chance there $\emph{will be rain}$ tomorrow?

## Solution

$2000\%$ is equivalent to $20\times100\%$. Therefore, $2000\%$ of a number is the same as $20$ times that number. $4$ quarters is $1$ dollar, so Bryden will get $20\times1={20}$ dollars, $\boxed{\text{A}}$.
