By definition, Direct variation equations have the following form:
[tex]y=kx[/tex]Where "k" is the Constant of variation.
For this case, you have the following equation:
[tex]y=11x[/tex]Where "x" is the the number of visits and "y" is the cost of visiting (in dollars).
In order to calculate the total amount a member will have paid on their 30th visit, you need to substitute this value into the equation:
[tex]x=30[/tex]Substituting into the equation and evaluating, you get:
[tex]\begin{gathered} y=11(30) \\ y=330 \end{gathered}[/tex]Therefore, the answer is: Third option.
