\n" ); document.write( "--------------
\n" ); document.write( "Cost:: 28
\n" ); document.write( "Revenue:: 4x
\n" ); document.write( "-----
\n" ); document.write( "Profit = Revenue - Cost
\n" ); document.write( "P(x) = 4x - 28
\n" ); document.write( "------
\n" ); document.write( "Solve:: 4x-28 = 20
\n" ); document.write( "4x = 48
\n" ); document.write( "x = 12 (# of containers needed)
