You can put this solution on YOUR website! Donna invested her $33,000 bonus and received a total of $970in interest after one year. If part of the money returned 4% and the remainder 2.25%, then how much did she invest at each rate?
---------------------
Let x be the amount invested at 4% and let y be the amount invested at 2/25%.
x+y=33000
0.04x + 0.0225y=970
