Hi there,
\n" ); document.write( "75 per 100 pens
\n" ); document.write( "Divide both sides by 100
\n" ); document.write( "0.075 per 1 pen
\n" ); document.write( "100% + 15% = 115% = 115/100 = 1.15
\n" ); document.write( "0.075 x 1.15
\n" ); document.write( "0.08625
\n" ); document.write( "This is what he must sell the pens
\n" ); document.write( "at to achieve 15% profit
\n" ); document.write( "Proof
\n" ); document.write( "0.08625- 0.075
\n" ); document.write( "=0.01125
\n" ); document.write( "0.01125/0.075 x 100 = 15% profit.
\n" ); document.write( "Hope this helps:-)
