P(n) = 70n - 1500....let me break this down for you
profit = revenue - expenses
so the revenue, what is made from selling tickets.....70n....where n represents the number of tickets....the 70 represents the cost of each ticket.
the 1500 is the expenses. So for them to make a profit, they would have to sell more then $ 1500 worth of tickets.
the price of a single ticket is $ 70 <==
