A = 2.25C (The theater sold 2.25 times as many adult tickets as child tickets.)
\n" ); document.write( "A + C = 260
\n" ); document.write( "Substitute the value of A
\n" ); document.write( "2.25C + C = 260
\n" ); document.write( "Add
\n" ); document.write( "3.25C = 260
\n" ); document.write( "Divide each side by 3.25
\n" ); document.write( "C = 80
\n" ); document.write( ".
\n" ); document.write( "If 80 children's tickets were sold, how many adult tickets?
\n" ); document.write( "A = 2.25C
\n" ); document.write( "2.25*80 = 180
\n" ); document.write( ".
\n" ); document.write( "Revenue:
\n" ); document.write( "80 children's tickets at $4 apiece (what a bargain!) = $320
\n" ); document.write( "180 adult tickets at $9 = $1620
\n" ); document.write( "Total gross sales = $320 + $1620 = $1940 <<--
\n" ); document.write( "
\n" );
