Question 1147235
.
<pre>
Let x be the amount invested at 6%.


Then the other amount is  (x+1000) dollars.


The total interest is the sum of partial interests


    0.06x + 0.02*(x+1000) = 660.


Express x and calculate


    x = {{{(660-0.02*1000)/(0.06 + 0.02)}}} = 8000  dollars.


<U>Answer</U>.  $8000 invested at 6%  and  8000+1000 = 9000 dollars invested at 2%.


<U>CHECK</U>.  0.06*8000 + 0.02*9000 = 660  dollas.    ! Precisely correct !
