Question 1202096
.
A certain type of piano costs the dealer $6,490. If the dealer wants to offer customers a discount of 15% off 
the price marked and still make a profit of 15%, what must be the marked price of the piano to the nearest dollar?
~~~~~~~~~~~~~~~~~


<pre>
Let x be the marked price, in dollars.


Then (x-0.15x) should be equal to  1.15*6490,  or  0.85x = 1.15*6490  dollars.


From this equation,  x = {{{(1.15*6490)/0.85}}} = 8780.5882.


It gives the <U>ANSWER</U> :  the marked price should be $8781  (rounded to the nearest dollar).
