The general formula is

where P = principal that becomes amount = A in 't' years at the rate I% compound interest per annum.

Here I is 8% per annum (12 months).
So I is 2% per quarter (3 months).
So time 't' will also be in quarters.

Put A = 30,000, I = 2 and t = 32 (since 32 quarters in 8 years) in the formula.
You get
or
=
= 15919 (approx)

Thus the $15919 will amount to $30,000 in 8 years at 8% rate compounded quarterly.
