An amusement park prices tickets at $55 and sells an average of 500 tickets daily. The management finds, over multiple increases in ticket pricing, that a $2 increase in the price of a ticket leads to an average ft 20 fewer tickets being sold in a day.
Management uses the combined function P to model the daily earnings of the amusement part, where x is the number of $2 increases in the price of a ticket.
P(X) = -40х2
- 100x + 27,500
