Question

In a village the cases of a particular infectious disease have been exponentially decreasing at a rate of 95% per year since the pople started receving the vaccine. If there were 200 cases in the village to start with, predict the number of cases after 2 years. First complete the equation:
Remaining amount=

Answer 1

The number of cases after two years is 221.

What is the number of cases after two years?

As a result of the disease, the population of the village would decrease by 95% per year. The number of cases at the village is function of the rate of infection, the number of years and the beginning number of cases.

The exponential function that can be used to represent this situation is:

FV = P( 1 + r)^t

• FV = Future value
• P =beginning number of cases
• R = rate of increase in the number of cases : 100% - 95% = 5%
• t = time

FV = 200 (1.05)^2 = 221
