Question 1168681
.
<pre>

Let x be the price for the desktop comp (before financial charges)

Then the price for the laptop is (x-200)  dollars, according the condition.



Now you write the TOTAL financial charges equation

    0.09*x + 0.07*(x-200) = 306  dollars.



From the equation

    x = {{{(306 + 0.07*200)/(0.09+0.07)}}} = 2000  dollars.



<U>ANSWER</U>.  $2000 for the desktop comp and $1800 for the laptop.
