The simple interest rate is 4.7%

<h3>How to determine the simple interest rate?</h3>

The given parameters are:

Principal = $2100

Interest = $1,559.46

Time = 15.8 years

The simple interest is calculated as:

I = PRT

Make R the subject

R = I/(PT)

So, we have:

R = 1559.46/(2100 * 15.8)

Evaluate

R = 0.047

Express as percentage

R = 4.7%

Hence, the simple interest rate is 4.7%
