document.write( "He bought 7 pens and 9 highlighters; each pen cost 3 times as much as a highlighter.  So what he spent was equivalent to 7(3)+9=30 highlighters, or 30/3=10 pens.<br><BR>\n" );
document.write( "He spent 1/4 of his money on that purchase, so he has 3/4 of his money left. When he spent 2/3 of his remaining money on more pens, he spent 2/3 of 3/4 of his original amount of money.<br><BR>\n" );
document.write( "2/3 of 3/4 of his original amount of money is 1/2 of his original money.  That is twice as much as he spent on the first purchase (1/2 is twice as much as 1/4), so this second purchase was enough to buy 2*10=20 more pens.<br><BR>\n" );
document.write( "So the total number of pens he bought was 7+20 = 27.<br><BR>\n" );
