Question 1155828
<br>
The amount invested at 9% is $44000 more than 4 times the amount invested at 6%:
x = amount invested at 6%
4x+44000 = amount invested at 9%<br>
The total interest is $47640:
{{{.06(x)+.09(4x+44000) = 47640}}}<br>
I don't know what the "six step method" is; presumably you do, and so can finish the problem from there.<br>
