You can put this solution on YOUR website!
for a 25% markup, the distributor's selling price (s) is 125% of the price he buys it for (b)\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "s = (125%)b ___ s = (1.25)b ___ s / 1.25 = b\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "the other values work the same way
\n" ); document.write( "
