.
<pre>

Let x be the lover rate, as the decimal value; then the higher rate is (x+0.005).


The basic equation is then


    (x+0.005)*14000 -x*7000 = 595  dollars.


Express x and calculate


    x = {{{(595-0.005*14000)/(14000-7000)}}} = 0.075.


<U>ANSWER</U>.  7.5% for $7000 and 8.0% for $14000.


<U>CHECK</U>.  0.08*14000 - 0.075*7000 = 595 dollars.   ! Precisely correct !
