3. In 1995, 1000 runners entered a marathon in Joppetown USA. In 1999, 23000 runners entered the race. Because of the limited number of facilities, the carrying capacity for the number of racers is 64000. The number of racers at any time, t, in years, can be modeled by the logistic function P(t) = C/1+Be^kt. In what year should at least 59000 runners be expected to run in the race?
