\n" ); document.write( "Formally....

\n" ); document.write( "x = adults
\n" ); document.write( "125-x = children

\n" ); document.write( "The total cost of the tickets, at $4 per adult and $1.75 per child, was $324.50:

\n" ); document.write( "4(x)+1.75(125-x) = 324.50

\n" ); document.write( "You can do the work to find the answer. (The algebra is basic, but the numbers are a bit ugly....)

\n" ); document.write( "Informally, using logical reasoning and simple arithmetic....

\n" ); document.write( "If all 125 tickets were adult tickets, the total cost would have been 125($4) = $500.
\n" ); document.write( "The actual total was $324.50, which is $175.50 less than $500.
\n" ); document.write( "The difference in the cost of an adult ticket and a child ticket is $4-$1.75 = $2.25.
\n" ); document.write( "The number of child tickets, to make the difference of $175.50, was 175.50/2.25 = 702/9 = 78.

\n" ); document.write( "ANSWER: 78 children's tickets and 125-78 = 47 adult tickets

\n" ); document.write( "CHECK: 78($1.75)+47($4) = 136.50+188 = 324.50

\n" ); document.write( "
\n" ); document.write( "
