3. The rate of change of the number of people who knows a certain rumor is proportional to the number of people who knows it and to the number of people who does not know it. A school has a population of 20,000. One person starts to spread a rumor. After 1 day, 15 people know about the rumor. Develop a model that predicts the number of people who knows the rumor. How many people will know of the rumor after 3 days? Approximately how many days will it take for everyone to know about the rumor?
