The number of years she had her investment is after 3 years

<h3>How to determine the years of investment?</h3>

From the question, the given parameters are:

  • Principal Amount, P = $400
  • Interest Rate, r = 1.72%
  • Simple Interest, I = $20.64

The number of years (T) is calculated from the following simple interest formula

I = PRT

Substitute the given parameters in the above equation

20.64 = 400 * 1.72% * t

Express 1.72% as decimal without percentage

20.64 = 400 * 0.0172 * t

Evaluate the product

20.64 = 6.88 * t

Divide both sides by 6.88

20.64/6.88 = 6.88/6.88 * t

Evaluate the quotient

3 = t

Rewrite the equation as

t = 3

This means that she had her investment after 3 years

Hence, the number of years she had her investment is after 3 years
