p = profit %
\n" ); document.write( "s = sale price
\n" ); document.write( "c = cost
\n" ); document.write( "---
\n" ); document.write( "p = ((s - c)/c)*100
\n" ); document.write( "p = (s/c - 1)*100
\n" ); document.write( "44 = (s/c - 1)*100
\n" ); document.write( "44/100 = s/c - 1
\n" ); document.write( "44/100 + 1 = s/c
\n" ); document.write( "s/c = 0.44 + 1
\n" ); document.write( "s/c = 1.44
\n" ); document.write( "---
\n" ); document.write( "answer:
\n" ); document.write( "s/c % = 1.44 * 100
\n" ); document.write( "s/c % = 144 %
