P (n) models the fundraiser's profit (in dollars) if n tickets are sold. A negative profit means the expenses exceeded the income from tickets.

P (n) = 70n-1500

what is the price of a single ticket

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 <==
