The number of tickets sold each day for an upcoming performance od Handel's Messiahis given by N(x)=-0.6x^2+18x+14, where x is the number of days since the concert first was announced. When will daily tickets peak and how many will be sold that day?
------
Maximum occurs when x = -b/2a = -18/(2*-0.6) = 15 (the day it peaks)
---
N(15) = -0.6(15)^2+18(15)+14 is the number sold.
N(15) = 149
