For #9, will I always get the right answer if I take the volume (32), divide it by the pressure (4), and multiply it by the rate (2)?

    Because I get the right answer doing that with this problem...

    I don't think so. I'm pretty sure that's an artifact of \(2^2=4\). Or something similar.

    Well, if we do the actual problem out, we get that \(c=128\). Then, we have that \[dV=-\;{128 \over P^2} dP\]We know that \(dP =2\) and \(P=4\). Solving, we find that \(dV =-16\). So really, it seems like it's because everything is just a power of two.

    For a counterexample, let \(V=40\). Then we get that \(dV =-35/2\) using the method I wrote out. Using your hypothetical method, we get that it would be \(-20\).
