**Kate**, Thursday, February 10, 2011 at 1:35pmIt depends a little on what math class you're in how they want you to solve this. But basically, this function is a parabola and you need to find the vertex.

x=-b/(2a), where a=-0.5, and b=12

x=-12/(2*-0.5)=12, this is the x coordinate of the vertex and also the number of days since the performance was announced. Then you substitute 12 in for x in the original equation:

-0.5(12)^2 + 12(12) + 13 = 85. This is the y coordinate of the vertex and the number of tickets sold.

So the daily tickets sales will peak 12 days after the performance was announced, with a maximum of 85 tickets sold that day.
