You can put this solution on YOUR website!
x = initial cost\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "x + 0.0635x = 5\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "1.0635x = 5\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "x = 5/1.0635\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "x = 4.70145745181007\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "x = 4.70 ... round to the nearest penny\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "So the item originally costs $4.70\r
\n" ); document.write( "
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( " \n" ); document.write( "
