Answer:
P = 10 + 1.06t
Explanation:
The problem gives you no clue as to where to start, so you can pick anyplace. The easiest solution is ...
P = P . . . . where P is the ticket price per person
__
If we assume you're supposed to factor in the tax and booking charge, you probably want to define t as the nominal ticket price. Then 1.06t will be the ticket price with tax added, and the cost of 2 tickets will be ...
two ticket cost = 20 + 2(1.06t)
The cost per person for two persons will be half this value, or ...
P = (two ticket cost)/2 = (20 +2(1.06t))/2
P = 10 + 1.06t . . . . . cost per person for tickets at price t
__
Many venues will sell tickets at a price with tax included. If that price is T, then the per-person price will be ...
P = (20 +2T)/2 = 10 + T
