You can put this solution on YOUR website!
m = s / c - 1
\n" ); document.write( "m% = s / c * 100\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "m is the profit margin
\n" ); document.write( "c is the cost.\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "when s = 850 and m = .15, m = s / c becomes .15 = 850 / c - 1\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "add 1 to both sides of this equation to get 1.15 = 850 / c\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "solve for c to get c = 850 / 1.15 = 739.1304348.\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "when m = .20, the formula of m = s / c - 1 becomes .20 = s / 739.1304348 - 1\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "add 1 to both sides of this equation to get 1.20 = s / 739.1304348.\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "solve for s to get s = 1.20 * 739.1304348 = 886.9565217.\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "that's your solution.\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "to get 20% profit, your sale price needs to be 886.9565217.\r
