12 $2.00 tickets and 8 $4.50 tickets.\r
\n" ); document.write( "\n" ); document.write( "Set the formula like this:
\n" ); document.write( "Let X = the number of $4.50 tickets, so (20-X)equals the number of $2 tickets.
\n" ); document.write( "The amount of money from $4.50 tickets would equal $4.5*(X) and the amount of $2 tickets would be $2*(20-X). Add those values together to equal $60.
\n" ); document.write( "(4.5*X) + (2*(20-X)) = 60 (distribute the 2 across the parenthesis)
\n" ); document.write( "4.5X + 40 - 2X = 60 (combine like terms)
\n" ); document.write( "2.5X + 40 = 60 (subtarct 40 from both sides)
\n" ); document.write( "2.5X = 20
\n" ); document.write( "X = 8 the number of $4.50 tickets, so (20-8) = 12, the number of $2 tickets.
