<PRE><B>Question 911941</B>
Total amount of money invested: $40000
x+y=40000,
Total yearly interest for the two accounts is: $2040
0.04*x+0.06*y=2040
x=40000-y
Substitute for x
0.04*(40000-y)+0.06*y=2040
Multiply out
1600-0.04*y+0.06*y=2040
Combine like terms.
0.02*y=440
Isolate y
y=$   22000.00 at 6% earns $1320 interest
x=40000-y
Calculate x
x=$   18000.00 at 4% earns $720 interest
Check
0.04*18000+0.06*22000=2040
720+1320=2040
2040=2040
If 2040=2040 is TRUE and neither x nor y  is negative then all is well
