Explanation
Simple interest is:
![s=P* r* t](https://img.qammunity.org/2023/formulas/mathematics/college/7syrqi60nxfq2v1zfao9ndjt4uhre31etn.png)
Where P is the principal amount, r is the rate of the interest per year and t is the number of years.
In this problem we have P = $4000, r = 0.02 and t = 3
The interest after 3 years will be:
![s=4000*0.02*3=240](https://img.qammunity.org/2023/formulas/mathematics/college/eceqbot3ozcs8vt6pspueipmx07c63zsnz.png)
