Directrix (directrix):

Simple interest is determined by multiplying the interest rate by the principal by the number of periods. I = 150.36 in interest r = 1.4% simple interest (assuming that it is a per year rate) t = 12 years I =P*r*t where P is principal, r is interest rate, and t is time

Directrix (directrix):

150.36 = P * .014 * 12

Directrix (directrix):

Solve for P. P = $ 895 @jorreh
