document.write( "\r\n" );
document.write( "Let x be the total population of the students at the school.\r\n" );
document.write( "\r\n" );
document.write( "\r\n" );
document.write( "Then 30% of the population is 0.3x.\r\n" );
document.write( "\r\n" );
document.write( "\r\n" );
document.write( "Therefore, from the condition, you have this equation\r\n" );
document.write( "\r\n" );
document.write( "\r\n" );
document.write( "    0.3x = 150.\r\n" );
document.write( "\r\n" );
document.write( "\r\n" );
document.write( "To solve it. divide both sides by 0.3.\r\n" );
document.write( "\r\n" );
document.write( "\r\n" );
document.write( "In this way, you will get\r\n" );
document.write( "\r\n" );
