Question

At a summer camp there is one counselor for every 9 campers. Determine whether there is a direct variation between the number of campers, y, and the number ofcounselors, x. If so, find the equation of direct variation.

Answer 1

`\begin{gathered} y=9x \\ \text{ Direct variation} \end{gathered}`

Explanation:

Since for every 9 campers there is one counselor, we can state:

`\begin{gathered} \text{Let y be the number of campers} \\ \text{Let x be the number of counselor} \\ y=9x \\ \text{ Exists a direct variation with a rate of change of 9 campers per counselor} \end{gathered}`
