Question 1080608: a man invests a certain amount of money at 2% interest and $800 more than that amount another account at 4% interest. At the end of one year, he earned $92 in interest. How much money was invested in each account? Answer by Boreal(15235) (Show Source):
You can put this solution on YOUR website! x at 2%
x+800 at 4%
.02x+.04(800+x)=92
.06x+32=92
.06x=60
multiply both sides by 100
6x=6000
x=$1000@2@=$20.
x+800=$1800@4%=$72
Total is $92.
