For this case we have that the variable "y" represents the total cost of the annual club membership.
For its part, the variable "x" represents the number of months.
Now, we have the following function:
[tex]y = 24x[/tex]
If you want to know the annual amount, then [tex]x = 12[/tex]
[tex]y = 24 * 12\\y = 288[/tex]
Thus, the total annual amount is 288 dollars.
ANswer:
$ 288
