Tickets to the school’s dinner theatre cost $6 for children and $9 for adults. 225 tickets were sold for a total of $1875
\n" ); document.write( "how many children attended?
\n" ); document.write( "how many adults attended\r
\n" ); document.write( "\n" ); document.write( "Let
\n" ); document.write( "Children attended = x
\n" ); document.write( "Adults attended = 225-x
\n" ); document.write( "Cost of Children's ticket = 6
\n" ); document.write( "Cost of Adult's ticket = 9
\n" ); document.write( "Total Amount of all tickets sold = 1875\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "(Children)(Cost of Children's ticket)+(Adults)(Cost of Adult's ticket)= Total Amount of all tickets sold
\n" ); document.write( "(x)(6)+(225-x)(9)=1875
\n" ); document.write( "6x+2025-9x=1875
\n" ); document.write( "-3x=1875-2025
\n" ); document.write( "-3x=-150
\n" ); document.write( "Divide by -3 both sides
\n" ); document.write( "-3x/-3=-150/-3
\n" ); document.write( "x=50\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "Children attended = x = 50
\n" ); document.write( "Adults attended = 225-x = 225-50=175\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( " \n" ); document.write( "
\n" );
