You can put this solution on YOUR website!
Let \r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "x = price of cheaper player\r
\n" ); document.write( "\n" ); document.write( "y = price of more expensive player\r
\n" ); document.write( "
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "Since \"One CD player is 3 times as much as another\", we can say (according to the definition made above)\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "y = 3x\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "Together the two CD players would be $320, so x and y must add to 320\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "x+y = 320\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "x + 3x = 320 .... plug in y = 3x\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "4x = 320\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "Solve for x. Then use it to find y. I'll let you finish up. \n" ); document.write( "

\n" );
