Answer:


p=96

Explanation:

Because p is inversely proportional to the square of q, we have that
p(q^2)=k for some constant k. We know that
p=6 when
q=8, so we have that
k=(6)(8)^2=6*64=384.

We want to know what p is when q is equal to 2, so we have that
p(2)^2=384, which gives
4p=384, which gives
\boxed{p=96}.

Note:
(96)/(6)=((8)/(2))^2. Coincidence?
