<PRE><B>Question 977688</B>
Total amount of money invested: $10000
x+y=10000,
Total yearly interest for the two accounts is: $508.75
0.045*x+0.055*y=508.75
x=10000-y
Substitute for x
0.045*(10000-y)+0.055*y=508.75
Multiply out
450.0-0.045*y+0.055*y=508.75
Combine like terms.
0.01*y=58.75
Isolate y
y=$    5875.00 at 5.5% earns $323.125 interest
x=10000-y
Calculate x
x=$    4125.00 at 4.5% earns $185.625 interest
Check
0.045*4125+0.055*5875=508.75
185.625+323.125=508.75
508.75=508.75
If 508.75=508.75 is TRUE and neither x nor y  is negative then all is well
