Question 1130774
<br>
We are told that the amount invested in bonds is $30000 more than the amount invested in CDs.  So<br>
let x = amount invested in CDS
then x+30000 = amount invested in bonds.<br>
The amount invested in stocks is what is left of the total investment of $140000:<br>
then 1400000-(x+x+30000) = 110000-2x is the amount invested in stocks.<br>
The total income from the investments, at the given rates, is $7392.50:<br>
{{{.0325(x)+.043(x+30000)+.065(140000-2x) = 7392.5}}}<br>
That is a straightforward linear equation in x; but the numbers are rather ugly.  If I were allowed to solve the problem by any means, I would graph the two expressions on either side of the equation on a graphing calculator and find the value of x where the graphs intersect; then of course use that value to find the amounts invested in each account.
