Mrs. Cook made deposits of $950 at the end of every 6 months for 15 years.
If interest is 3% compounded monthly, how much will Mrs. Cook have accumulated
10 years after the last deposit?
~~~~~~~~~~~~~~~~~~

The nominal interest is 3% compounded monthly.


It means that the monthly effective growth factor is  (1+0.03/12) = 1.0025.


Then the semi-annual effective growth factor is  =  = 1.01509406308652.


So, we can now write the formula for the future value of the ordinary annuity in 15 years 
with the semi-annual deposits of $950 at the end of every 6 months with the found effective 
rate

    FV =  = 35713.39  (rounded).


In 10 years after that the accumulated amount will be

     = 48189.99.


ANSWER.  In 10 years after the last deposit, the accumulated amount will be about 48190 dollars.

Solved.
