In a city with 500,000 population, the rate of the spread of a new flu epidemic is proportional to both number of people who have contracted the disease and the number of people who have not contracted it. If there are 500o flu cases at the start of the outbreak and 2,000 flu cases after 4 weeks, how many flu cases are expected after 10 weeks? 8,986 10,283 12,846 15,632
