Question

The cost of visiting y varies directly with the number of visits x, according to the equation y=11x what is the total amount a member will have paid on their 30th visit.$41$2.73$330$0.37

Answer 1

By definition, Direct variation equations have the following form:

`y=kx`

Where "k" is the Constant of variation.

For this case, you have the following equation:

`y=11x`

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:

`x=30`

Substituting into the equation and evaluating, you get:

`\begin{gathered} y=11(30) \\ y=330 \end{gathered}`

Therefore, the answer is: Third option.
