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
(1) When c>= 100, b>=50
(2) When c=100, a=100
