he makes 10 durians for 30 dollars.\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "he sells each durian for 7 dollars.\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "let x = the number of durians he sells.\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "his revenue is 7 * x.\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "his cost is 30.\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "his revenue must be greater than his cost to make a profit, so you get:\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "7 * x >= 30\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "solve for x, and you get x >= 30/7 which becomes x >= 4 and 2/7.\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "since he can't sell part of a durian, than x >= 5 is the answer.\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "when he sells 4 durians, he makes 28 dollars.\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "when he sells 5 durians, he makes 35 dollars.\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "he starts making a profit when he sells at least 5 durians.\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( " \n" ); document.write( "
\n" );
