how did u get that anwser
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
