Problema Solution

Given interest of $11,900 at 6% for 50 days (ordinary interest), one can calculate the principal as __________.

Answer provided by our tutors

Ordinary interest is an interest that is calculated on a 360-day-a-year basis.

Let 'P' represent the principal.

I = $11,900 is the interest

r = 0.06 or 6% is the annual rate

t = 50 days = 50/360 years the time

The formula for the interest is:

I = P*r*t

11900 = P*0.06*(50/360)

P*0.06*(50/360) = 11900
