"thank you so much. i really want to understand this investments." Answer by richwmiller(17219) (Show Source):
You can put this solution on YOUR website! x+y=25000,
0.03*x+0.045*y=900
x=25000-y
0.03*(25000-y)+0.045*y=900
750-0.03y+0.045*y=900
0.015*y=150
y= 10000
x=25000-y
x=15000
check
0.03*15000+0.045*10000=900
450+450.0=900
900.0=900
ok
