Let A be the number of adult tickets at $8 each.
\n" ); document.write( "Let S be the number of student tickets at $5 each.
\n" ); document.write( "a.)
\n" ); document.write( "\"1800 total tickets sold\"
\n" ); document.write( "1.\"A%2BS=1800\"
\n" ); document.write( "\"for a total of $12750\"
\n" ); document.write( "2.\"8A%2B5S=12750\"\r
\n" ); document.write( "\n" ); document.write( "b.) Solve eq. 1 for A in terms of S.
\n" ); document.write( "1.\"A%2BS=1800\"
\n" ); document.write( "\"A=1800-S\"
\n" ); document.write( "Now substitute this expression into eq. 2 and solve for S,
\n" ); document.write( "2.\"8A%2B5S=12750\"
\n" ); document.write( "\"8%281800-S%29%2B5S=12750\"
\n" ); document.write( "\"14400-8S%2B5S=12750\"
\n" ); document.write( "\"-3S=-1650\"
\n" ); document.write( "\"S=550\"
\n" ); document.write( "From above,
\n" ); document.write( "\"A=1800-S\"
\n" ); document.write( "\"A=1800-550\"
\n" ); document.write( "\"A=1250\"
\n" ); document.write( "There were 1250 adult tickets sold and 550 student tickets sold.
\n" ); document.write( "d.)
\n" ); document.write( "1.\"A%2BS=1800\"
\n" ); document.write( "1.\"1250%2B550=1800\"
\n" ); document.write( "1.\"1800=1800\"
\n" ); document.write( "True.
\n" ); document.write( "2.\"8A%2B5S=12750\"
\n" ); document.write( "2.\"8%281250%29%2B5%28550%29=12750\"
\n" ); document.write( "2.\"10000%2B2750=12750\"
\n" ); document.write( "2.\"12750=12750\"
\n" ); document.write( "True.
\n" ); document.write( "
\n" );
