\n" );
document.write( "Hi,
\n" );
document.write( "Let b represent the number of blue cups and r the number of red cups originally purchased
\n" );
document.write( "amount of each left is equal according to the question
\n" );
document.write( "2/3 * b = 1/2* r  
\n" );
document.write( "4/3 *b = r
\n" );
document.write( "b + r = 280
\n" );
document.write( "b + (4/3)b = 280
\n" );
document.write( "(7/3)b = 280
\n" );
document.write( "b = 280*(3/7)
\n" );
document.write( "b = 120, the original amt of blue cups purchased.  Red = 160 (280-120)
\n" );
document.write( "How many used?
\n" );
document.write( "1/3*120 + 1/2*140 = 40 + 70 = 100 \n" );
