<PRE><B>Question 1104748</B>
This works like a mixture problem.


x, how much in 6% rate account
20000-x, how much in 5% rate account


Amount of interest earned was  $1170.

{{{0.06*x+0.05(2000-x)=1170}}}, equation to account for the two interest amounts.

-

{{{6x+5(20000-x)=117000}}}
{{{6x+100000-5x=117000}}}
{{{x=117000-100000}}}
{{{highlight(x=17000)}}}-----------to invest in the 6% rate account.


{{{highlight(3000)}}}------------to invest at the 5% rate.
