let the restoration fee to be X
we dont need 19 tickets right ?? we just need one for you :--)
So, 223.25/19 = $11.75 <----( the price for your single ticket.
since this is the whole thing for concert, program and restoration fees
the 11.75=X+6.70+4.20
==> X=11.75 - (6.70+4.20) ==> X= $0.85 is your restorqtion fees
