I encountered this problem while taking the Princeton Review Practice Test. Any pointers to the solution will be appreciated. I cannot understand the explanation given by PR on this.
Thanks in advance,

Q) At RW Press, the advertising rate, a, is inversely proportional to the productivity measure, b, which, in turn, is inversely proportional to the labor cost, c. Is the labor cost at least 200 when the productivity measure is at least 100?
(1) When c >= 100, b>= 50
(2) When c=100, a=100
