Answer:
Step-by-step explanation:
The rate of infection is jointly proportional to the number of infected troopers and the number of non-infected ones. It can be expressed as follows:
Rearranging and integrating
At the initial breakout (t=0) there was one trooper infected (I=1)
In two days (t=2) there were 5 troopers infected
Rearranging, we can model the number of infected troops (I) as
