\n" ); document.write( "c = .6s
\n" ); document.write( " &
\n" ); document.write( "10% of sale price ûexceeds 15% of the cost by to 10.
\n" ); document.write( ".10s = .15c + 10
\n" ); document.write( "replace c with .6s
\n" ); document.write( ".10s = .15(.6s) + 10
\n" ); document.write( ".10s = .09s + 10
\n" ); document.write( ".10s - .09s = 10
\n" ); document.write( ".01s = 10
\n" ); document.write( "s = 10/.01
