In a population of 100,000 people, 10,000 are infected with a virus. After a person becomes infected and then recovers, the person is immune (cannot become infected again). OF people who are infected, 3% will die each year and the others will recover. Of the people who have never been infected, 25% will become infected each year.

### Infection and Immunity Simulation Problem

In a population of 100,000 people, 10,000 are infected with a virus. After a person becomes infected and then recovers, the person is immune (cannot become infected again). Of the people who are infected, 3% will die each year and the others will recover. Of the people who have never been infected, 25% will become infected each year. How many people will be infected in 4 years? (Round your answer to the nearest whole number.)

**Diagram Explanation:**
There are no diagrams or graphs included in this problem. The problem involves calculating the number of people who will be infected given a set of infection and recovery rules over a period of 4 years.

**Solution Storyline:**
1. From the initial 100,000 people:
   - 10,000 are initially infected.
2. Of the infected people (10,000):
   - 3% will die each year.
   - The rest will recover and become immune.
3. Of the non-infected population (90,000):
   - 25% will get infected each year.

**Inputs:**
- Total population = 100,000
- Initially infected = 10,000
- Initial non-infected = 90,000

**Yearly Calculations:**
- For each subsequent year until 4 years:
   - Calculate deaths among infected.
   - Subtract deaths from the infected count.
   - Calculate new infections from those initially non-infected.

> Follow the arithmetic steps for precise calculations for yearly changes over 4 years, rounding the final answer to the nearest whole number.
