A capital of \( € 42000 \) is paid into a bank with a \( 5 \% \) annual interest rate. How much money will there be after a year? And after two years? And after three years?

The formula for simple interest is \( I=P r t \), where \( P= \) principal, \( r= \) rate, and \( t= \) time. Solve the formula for \( r \). \( \begin{array}{l} r=\frac{t I}{P} \\ r=\frac{P t}{l} \\ r=\frac{P I}{t} \\ r=\frac{l}{P t}\end{array} \)
