Question 1189962
.
Mrs. Dimawala loaned P15,000 on February 16, 2006 and promised to pay 
after 200 days with interest at 15% simple interest. 
How much will Mrs. Dimawala pay on the due date? When is the due date ?
~~~~~~~~~~~~~~~~


<pre>
Use the simple interest formula


    A = P(1+r*t),


where P is the loaned amount, r is the simple interest rate as decimal, t is the time in years,
A is the amount to pay back.


In your problem, P = 15,000;  r = 0.15;  t = {{{200/365}}} = 0.547945205 of an year.



Therefore, the answer is  A = 15000*(1+0.15*0.547945205) = P 16,232.88.
