Answer:
$40
Step-by-step explanation:
The below formula can be used to find the simple interest;
![I=(P* r* t)/(100)](https://img.qammunity.org/2023/formulas/mathematics/college/7kcepolwm39mvizhmxb3dhy5oscwzud0y6.png)
where I = Interest
P = principal amount = $500
r = rate = 2%
t = time = 4 years
Let's go ahead and substitute the given values into the formula and solve for I;
![I=(500*4*2)/(100)=40](https://img.qammunity.org/2023/formulas/mathematics/college/6qu8ojq5cp3egupvpus9ojg3bxyxd8u15h.png)
