Explanation:

Step1: Calculate the raise amount

We need to find 12.4% of $20.59. The formula for finding a percentage $p$ of a number $n$ is $n\times\frac{p}{100}$. Here, $n = 20.59$ and $p=12.4$. So the calculation is $20.59\times\frac{12.4}{100}$. $20.59\times\frac{12.4}{100}=20.59\times0.124$

Step2: Perform the multiplication

$20.59\times0.124 = 2.55216$

Step3: Round to the nearest penny

Rounding $2.55216$ to the nearest hundred - th (penny), we get $2.55$.
