This problem should state the cost of a child's ticket and the cost of an adult ticket.
\n" ); document.write( "2a=c
\n" ); document.write( "a*(the cost of an adult ticket)+c*(the cost of a child's ticket equals=1080
\n" ); document.write( "sub in 2a for c\r
\n" ); document.write( "\n" ); document.write( "a*(the cost of an adult ticket)+2a*(the cost of a child's ticket equals=1080
\n" ); document.write( "combine like terms and solve the equation for a. Plug in what you get for a into the original equation
\n" ); document.write( "
\n" );
