<PRE><B>Question 911400</B>
Total amount of money invested: $6600
x+y=6600,
Total yearly interest for the two accounts is: $426
0.03*x+0.09*y=426
x=6600-y
Substitute for x
0.03*(6600-y)+0.09*y=426
Multiply out
198-0.03*y+0.09*y=426
Combine like terms.
0.06*y=228
Isolate y
y=$    3800.00 at 9% earns $342 interest
x=6600-y
Calculate x
x=$    2800.00 at 3% earns $84 interest
Check
0.03*2800+0.09*3800=426
84+342=426
426=426
If this statement is TRUE and neither x nor y  is negative then all is well
