A concert promoter needs to take in $380,000 on the sale of 16,000 tickets. If the promoter charges $20.00 dollars for some tickets and $30.00 for others, how many of each type must be sold to take in the $380,000?

\n" ); document.write( "Quantity: t + r = 16000 tickets
\n" ); document.write( "Value: 20t +30r = 380,000 dollars
\n" ); document.write( "------------------------------------
\n" ); document.write( "2t + 2r = 32000
\n" ); document.write( "2t + 3r = 38000
\n" ); document.write( "------------------------
\n" ); document.write( "Subtract and solve for \"r\":
\n" ); document.write( "r = 6000 (# of $30 tickets sold)
