You can put this solution on YOUR website!
Let \"x\" = ticket for adults
\n" ); document.write( "\"y\" = ticket for students
\n" ); document.write( "So $\"x%2By=240+tickets\"$ ------> eqn 1
\n" ); document.write( "Also
\n" ); document.write( "($4x)+($2.50y) = $765.00 ------> eqn 2
\n" ); document.write( "In eqn 1 we get, $\"x=240-y\"$ then substitute this in eqn 2,
\n" ); document.write( "4(240-y) + 2.50y = 765
\n" ); document.write( "960-4y + 2.50y = 765
\n" ); document.write( "960-765=4y-2.50y
\n" ); document.write( "195=1.5y
\n" ); document.write( " $\"y=130+tickets+for+students\"$
\n" ); document.write( " $\"x=240-130=110+tickets+for+adults\"$
\n" ); document.write( "in doubt? Go back eqn 2,
\n" ); document.write( "$4(110) + $2.50(130) = $765
\n" ); document.write( "$440 + $325 = $765
\n" ); document.write( "$765 = $765
\n" ); document.write( "Thank you,
\n" ); document.write( "Jojo \n" ); document.write( "
