\n" ); document.write( "an art museum sold 63 tickets in 30 minutes. The ratio of adult to child tickets was 5:1. The ratio of adult to senior tickets was 5:3. How many of each kind of ticket were sold?
\n" ); document.write( "

Let number of children, adults, and seniors be C, A, and S, respectively
\n" );
document.write( "Since children to adults, or C:A = 1:5, it follows that: 
\n" );
document.write( "Since adults to seniors, or A:S = 5:3, then 
\n" );
document.write( "                                             ------ Replacing A with 5C

document.write( "With total number of attendees being 63, we then get: C + A + S = 63, or C + 5C + 3C = 63
