interest is 67.50 and rate is 3%, and time is 3 years. What is the principal?

if simple interest ....

P = 67.5/(.03(3)) = 750

To find the principal, we can use the formula for simple interest:

Simple Interest = (Principal * Rate * Time) / 100

Here, the simple interest is given as $67.50, the rate is 3%, and the time is 3 years.

Substituting these values into the formula, we have:

67.50 = (Principal * 3 * 3) / 100

To find the principal, we can rearrange the equation:

Principal = (67.50 * 100) / (3 * 3)

Principal = 2250 / 9

Principal ≈ 250

Therefore, the principal is approximately $250.
