Question 1114606
<br>
The amount invested in A bonds at 10% yield is x; the amount invested in AAA bonds at 6% yield is 2x; the rest, $50,000-3x, is invested in AA bonds at 7% yield.<br>
The total income from the investments is $3620.<br>
{{{.10(x)+.06(2x)+.07(50000-3x) = 3620}}}<br>
You can solve that with simple algebra....
