A varies directly as b and inversely as the square of c. If a = 197 when b = 5 and c = 5, find a if b = 3 and c = 3

With the information you provided, we can find an equation.

A=kB / (C^2) (k is a constant)

197 = 5k / (5^2)

197=5k/25

197=k/5

k = 985

So find a if b=3 and c=3

A = 3 (985) / (3^2)

A = 2955/9 is your answer.
