Answer:
b = 125
Step-by-step explanation:
Given a varies directly as then the equation relating them is
a = k ← k is the constant of variation
To find k use the condition a = 3 , b = 64 , then
3 = k = 4k ( divide both sides by 4 )
= k
a =
← equation of variation
When a = , then
=
( multiply both sides by 4 to clear the fractions )
15 = 3 ( divide both sides by 3 )
5 = , then
b = 5³ = 125
