The Little Town Arts Center charges $21 for adults, $17 for senior citizens and $8 for children under 12 for their live performances on Sunday afternoon. This past Sunday, the paid revenue was $13,274 for 886 tickets sold. There were 47 more children that adults. How many children attended?
\n" ); document.write( ".
\n" ); document.write( "Let x = number of adult tickets
\n" ); document.write( "then \"There were 47 more children that adults.\"
\n" ); document.write( "x+47 = number of children's tickets
\n" ); document.write( "and from: \"886 tickets sold\"
\n" ); document.write( "886-(x + x+47) = 886-(2x+47) = 839-2x = number of senior tickets
\n" ); document.write( ".
\n" ); document.write( "Our equation comes from: \"the paid revenue was $13,274\"
\n" ); document.write( "21x + 17(839-2x) + 8(x+47) = 13274
\n" ); document.write( "21x + 14263-34x + 8x+376 = 13274
\n" ); document.write( "-5x + 14639 = 13274
\n" ); document.write( "-5x = -1365
\n" ); document.write( "x = 273 (number of adult tickets)
\n" ); document.write( ".
\n" ); document.write( "number of children's tickets:
\n" ); document.write( "x+47 = 273+47 = 320
\n" ); document.write( ".
\n" ); document.write( "number of senior tickets:
\n" ); document.write( "839-2x = 839-2(273) = 839-546 = 293
\n" ); document.write( "
\n" ); document.write( "
