Question 114570: Find the constant of variation k.
m varies directly with n; m=144 when n=8.
This is what I have; m=kn (144)=k8 k=18
Am I close on this at least a little? Thank you for your help.

You are correct. Now let's check our answer:

m=18n Start with the equation (remember the general equation is m=kn where in this case k=18)

144=18%288%29 Now plug in m=144 and n=8


144=144 Multiply. Since both sides of the equation are equal, our answer is verified.
