Question 1137199
.
<pre>
Let x= amount invested at 4%.


Then the total interest equation is


0.05*(2x) + 0.04*x = 364


0.1x + 0.04x = 364


0.14x = 364  ==========>  x = {{{364/0.14}}} = 2600.


<U>ANSWER</U>.  $2600 invested at 4%;  Twice of it,  $5200 invested at 5%.


<U>CHECK</U>.   0.04*2600 + 0.05*5200 = $364.   ! Correct !
