31000 dollars were invested at 4% interest rate.

16000 dollars were invested at 5% interest rate.

Step-by-step explanation:

Convert the interest rate into decimal and then write down two equations to solve for the unknowns.

$\begin{bmatrix}0.04x+0.06y=2200\\ x+y=47000\end{bmatrix}$

$\mathrm{The\:solutions\:to\:the\:system\:of\:equations\:are:}\\\\x=31000,\:y=16000$
