Tickets for an event cost $4 for children, $12 for adults, and $7 for senior citizens. The total ticket sales were $1920. There were 50 more adult tickets sold than child tickets, and the number of senior citizens tickets were 4 times the number of child tickets. How many of each ticket were sold?
\n" ); document.write( "-------------
\n" ); document.write( "Let number of child tickets be \"x\"; their value is 4x dollars.
\n" ); document.write( "Number of adult tickets is \"x+50\" ; their value is 12(x+50)=12x+600 dollars
\n" ); document.write( "Number of senior tickets is \"4x\" ; their value is 7(4x)=28x dollars
\n" ); document.write( "--------------
\n" ); document.write( "EQUATION:
\n" ); document.write( "value + value + value = 1920 dollars
\n" ); document.write( "4x+12x+600+28x=1920
\n" ); document.write( "44x=1320
\n" ); document.write( "x=30 (# of child tickets)
\n" ); document.write( "x+50=80 (# of adult tickets)
\n" ); document.write( "4x=120 (# of senior tickets)
