In a particular town a population A, 20 percent of the residents heard a radio announcement about a local political scandal on their way to work at 7:00 a.m. If 50 percent of the population had heard about the scandal by 8:00 a.m., what time was it when 80 percent of the population had heard about it?
Let P(t) persons hear about the scandal after t hours, where P(t) = A / ( 1 + Be-Akt)
Note: The "-Akt" is the power on e.
