\n" ); document.write( "\n" ); document.write( "

Let N = the number of sessions you will need.\r\n" );
document.write( "\r\n" );
document.write( "If you don't become a member then your total cost for\r\n" );
document.write( "the N sessions will be $5N\r\n" );
document.write( "\r\n" );
document.write( "If you do become a member then your total cost for the\r\n" );
document.write( "N sessions will be $25 + $3N\r\n" );
document.write( "\r\n" );
document.write( "Now we set those equal to each other to find the value\r\n" );
document.write( "of N when they will cost the same.\r\n" );
document.write( "\r\n" );
document.write( "      5N = 25 + 3N\r\n" );
document.write( "\r\n" );
document.write( "That's the equation.  We solve it\r\n" );
document.write( "\r\n" );
document.write( "      2N = 25\r\n" );
document.write( "       N = 12.5\r\n" );
document.write( "\r\n" );
document.write( "That's halfway between two integers, 12 and 13.\r\n" );
document.write( "\r\n" );
document.write( "Interpretation.  If you will need 12 or fewer sessions, then\r\n" );
document.write( "you should not become a member.  But if you will need 13 or\r\n" );
document.write( "more sessions, then you should become a member.\r\n" );
