In a city having a fixed population of P persons, the time rateof change of the number N of those people who have heard a certainrumor is proportional to the number of those who have not yet heardthe rumor. After the rumor was started, a poll found that 15% ofthe population had heard the rumor after 5 days. Write adifferential equation that models this phenomenon with P = 6100000,N(0) = 5600.
