Let Tamara invests amount $X$ in 3% account. She invests $8000-X$ in 2% account.

The interest after t years is given by

$I=Prt$ . After 1 year the two interests are equal, that is

$X(\frac{3}{100}) (1)=(8000-X)(\frac{2}{100}) (1)\\ 3X=2(8000-X)\\ 5X=16000\\ X=3200$

Thus, Tamara has to invest $\$3200$ in 3% account and $\$8000-\$3200=\$4800$ in 2% account.
