\n" ); document.write( ";
\n" ); document.write( "Let x = purchase price
\n" ); document.write( "then
\n" ); document.write( "2x = selling price
\n" ); document.write( ":
\n" ); document.write( "Revenue - cost = profit
\n" ); document.write( "2x(60-3) - 60x = 1188
\n" ); document.write( ":
\n" ); document.write( "2x(57) - 60x = 1188
\n" ); document.write( ":
\n" ); document.write( "114x - 60x = 1188
\n" ); document.write( "54x = 1188
\n" ); document.write( "x = 1188/54
\n" ); document.write( "x = $22 the purchase price
\n" ); document.write( "then
\n" ); document.write( "$44 price they sold them for
\n" ); document.write( ":
