How to solve proportional relationships word problems?

I am not sure but this is a example Step 1) Proportional quantities have a constant ratio and can be described by the equation y = kx, where k is a constant ratio. The constant of proportionality is the coefficient of x or the independent variable. 
 
Step 2) We have the constant of proportionality as 
p = .35n
We can conclude that .35 is the coefficient of variable ‘n’.
