Since 2010, when 102390 Cases were reported, each year the number of new flu cases decrease to 85% of the prior year. Predict the number of cases that will be reported in 2020 and the trend continues

20,158 cases

Step-by-step explanation:

Let represent year 2010.

We have been given that since 2010, when 102390 Cases were reported, each year the number of new flu cases decrease to 85% of the prior year.

Since the flu cases decrease to 85% of the prior year, so the flu cases for every next year will be 85% of last year and decay rate is 15%.

We can represent this information in an exponential decay function as:

To find number of cases in 2020, we will substitute in our decay function as:

Therefore, 20,158 cases  will be reported in 2020.
