Chapter 3.4, Problem 107E

Epidemic outbreak. The number of people in a community who became infected during an epidemic t weeks after its outbreak is given by the function f ( t ) = 20 , 000 1 + a e − k t ,

where 20 , 000

people of the community are susceptible to the disease. Assuming that 1 , 000 people were infected initially and 8 , 999 had been infected by the end of the fourth week.

a. Find the number of people infected after eight weeks.

b. After how many weeks will 12 , 400

people be infected?
