Question 317920: I need help finding the variation constant.

n varies directly as q, and n = 39 when q = 3. Find n when q = 8.

You can put this solution on YOUR website!
n varies directly as q
n = kq
----
Solve for "k" using
n = 39 when q = 3.
---
39 = k*3
k = 13
----
Therefore the equation for this
relation is n = 13q
------
Find n when q = 8
---
n = 13*q
n = 13*8
n = 104
