Question 44981: this is a different one our instructor wrote for us. I have not a clue how to begin.
at these prices it is estimated that the number of customers is related to the amount of time they must wait as,
N = -5t(squared)+80t-280, where t is time in minutes. When there are 35 customers what is the estimated wait time? Answer by tutorcecilia(2152) (Show Source):
You can put this solution on YOUR website! N = -5t(squared)+80t-280, where t is time in minutes. When there are 35 customers what is the estimated wait time?
N =35
35= -5t(squared)+80t-280
35 - 35 = -5t(squared)+80t-280-35 [Set the equation equal to zero]
0=-5t(squared)+80t-315 [solve using the quadratic formula]

.-80+-10/-10
.-80+10/-10t = 7 minutes
.-80-10/-10 =9 minutes
Taking the average 9+7/2 = 8 minutes
