You can put this solution on YOUR website! If A varies directly as 1/B
A = k(1/B) = k/B
----------
Need to find "k"
given that A = 117 when B = 83.4, evaluate:
117 = k/83.4
k= 117*83.4
k = 9757.8
EQUATION:
A = 9757.8/B
----------------
Find B when A = 63.2.
63.2 = 9757.8/B
B = 9757.8/63.2
B = 154.3955...
