Direct And Inverse Variation Example 1

Here is an example of how to solve a direct and inverse variation problem.  Remember to read the lesson on this topic.

Basic steps to follow:

1. First understand that variation problems are basically equation problems; know the difference between direct and inverse variation
2. Next use the data in the problem to find the constant of variation = k; if you have the value for k then set up the equations y=kx for direct and yx=k for inverse.
3. Use the equation (with the k value) to find the missing value- i.e. you will be solving for x or y
