You need to supply information about projected ticket sales to the box office manager. The box office manager uses this information to anticipate staffing needs until the tickets sell out. You provide the manager with a quadratic equation that models the expected number of ticket sales for each day x. (x=1 is the day tickets go on sale).
Tickets = -0.2x^2 + 12x + 11
use the quadratic equation to determine the last day the tickets will be sold. (Note: write your answer in terms of the number of days after ticket sales begin).
Now, for some reason I can't seem to get started on this problem...would someone give me a kick in the right direction? (Headbang)

are they just asking you to find the zeroes of this function? The question is not worded very well. Use the quadratic formula.
I got around -.9 and 60.9. clearly can't be the negative one, so I would guess like day 61 would be when tickets are sold out? I am not sure though
