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

6x + 2y = 18
2y = -6x + 18
y = -3x + 9
