Let S = the number of student tickets sold and A = the number of adult tickets sold.
\n" ); document.write( "From the problem, you can write:
\n" ); document.write( "1) S+A = 285 \"A total of 285 (student plus adult) tickets were sold...\"
\n" ); document.write( "2) S = 2A \"The number of student tickets (S) sold was two times the number of adult tickets (A) sold.\"
\n" ); document.write( "Substitute equation 2) (S = 2A) for S in equation 1).
\n" ); document.write( "(2A+A) = 285 Simplify.
\n" ); document.write( "3A = 285 Divide both sides by 3.
\n" ); document.write( "A = 95 This is the number of adult tickets sold.
\n" ); document.write( "From equation 2)...
\n" ); document.write( "S = 2A
\n" ); document.write( "S = 2(95)
\n" ); document.write( "S = 190 This is the number of student tickets sold.
\n" ); document.write( "
\n" );
