0.08x+0.09y=10,437
C) x+y=10,437
0.08x+0.09y=849.52

You can put this solution on YOUR website! The answer is C. Let's think about this.
The total interest earned is $849.52
The interest rates are 8% and 9%. This means whatever amount invested at 8% plus the amount invested at 9% equals this number or:
.08x+.09y=$849.52
The total after is the amount of the two account or x+y.
