Work Step by Step
According to the question, the initial value of infected people is y_{0}=20000.
We also know that the question is asking for the value of infected people after 3 weeks, which means that our t value is t=3. Substituting this into the equation, we get the following:
y = y_{0}\timese^{0.075\times3}
y = 20000\timese^{0.225}
y = 25046.45 \approx 25046 people
