Question 1190651
.
<pre>

I used the same general formula, but I did not round  r = 0.2/365:  I kept it as is.


So, my formula was


    FV = 50 * [ ((1 + 0.2/365)^30 - 1) / (0.2/365) ].


It provides more precise calculations and makes final rounding only at the very end.



    In such calculations, making rounding at the very end only 
    and do not making intermediate rounding is critically important 
    for precision and is STRONGLY RECOMMENDED.
    Intermediate rounding like 0.20 / 365 ≈ 0.0005479, as the other tutor makes,
    is traditionally considered as a non-appropriate way.



Also, I used MS Excel as my calculator.  It works with 15-bit numbers.


My answer is 1511.99 pesos.
