Total tickets sold = 13,900
\n" ); document.write( "Tickets sold for above 8 years old = x
\n" ); document.write( "Tickets sold for under 8 years = 13,900-x
\n" ); document.write( "Cost of a ticket above 8 years old = $20
\n" ); document.write( "Cost of a ticket under 8 years old = $5
\n" ); document.write( "Total sell = $197,000\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "(Tickets sold for above 8 years old)* (Cost of a ticket above 8 years old)+(Tickets sold for under 8 years)*(Cost of a ticket under 8 years old) = Total sell
\n" ); document.write( "x*20+(13,900-x)*5=197000
\n" ); document.write( "20x+69500-5x=197000
\n" ); document.write( "20x-5x=197000-69500
\n" ); document.write( "15x=127500
\n" ); document.write( "x=127500/15
\n" ); document.write( "x=8500\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "Tickets sold for above 8 years old = 8500
\n" ); document.write( "Tickets sold for under 8 years = 13,900-8500 = 5400\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "Check
\n" ); document.write( "=======
\n" ); document.write( "5400 * 5 + 8500 * 20 = 197000
\n" ); document.write( "27000+170000=197000
\n" ); document.write( "197000=197000
