When will daily ticket sales peak and how many tickets will be sold that day Answer by ankor@dixie-net.com(22740) (Show Source):
You can put this solution on YOUR website! The number of tickets sold each day for an upcoming event is given by N(x)=-0.5x^2+13x+13,
where x is the number of days since the concert was first announced.
When will daily ticket sales peak and how many tickets will be sold that day
:
N(x)=-0.5x^2+13x+13 is a quadratic equation, max sales occur at the axis of symmetry
Find the axis symmetry with the formula x = -b/(2a)
In this equation: a=-.5, b=13
x =
x = +13 days after announced it will be at peak sales
:
Find peak sales, replace x with 13
N(x)=-0.5(13^2)+13(13)+13
N(13) = -84.5 + 269 + 13
N(13) ~ 97 ticket sold on that day
