First, you need to calculate 2 rates:

Rate x: the annual rate equivalent to 6.8 cpd quarterly (use with annual deposits)

Rate y: the monthly rate equivalent to this annual rate (use with monthly deposits)

x = (1 + .068/4)^4 - 1

y = (1 + x)^(1/12) - 1

Formula = d[(1 + i)^n - 1] / i

d = regular deposit

i = periodic interest rate

n = number of periods

Value after 25 years:

With annual deposits of $3600:

3600[(1 + x)^25] / x

With monthly deposits of $300:

300[(1 + y)^300] / y

There ya go, MissL.

If you can't follow above, you need a face to face teacher.
