Algebra.Com's Answer #2254 by longjonsilver(2297)![]() ![]() You can put this solution on YOUR website! Percentage calculations are always done against the original..not the final answer, so lets call the original price x.\r \n" ); document.write( " \n" ); document.write( "\n" ); document.write( "20% discount from x is (20/100)x or 0.2x. This discount is taken off the original, x, so we have x-0.2x which is 0.8x and this is the sales price of 12590.\r \n" ); document.write( " \n" ); document.write( "\n" ); document.write( "So 0.8x = 12590 \n" ); document.write( "x = 12590/0.8 \n" ); document.write( "--> x, the original price = $15737.50\r \n" ); document.write( " \n" ); document.write( "\n" ); document.write( "Hope this explains it simply enough for you?\r \n" ); document.write( " \n" ); document.write( "\n" ); document.write( "jon. \n" ); document.write( " \n" ); document.write( " |
