Your gym membership costs $33 per month after an initial membership fee . you paid a total of $228 after 6 months.
(a) write an equation that gives you the total cost related to the months of your gym membership
(b)find the total cost after 9 months?

So, what I did was multiply 33*6 and got 198 and then 228-198 to find out that the initial fee was 30 dollars. then multiply 33*9+30 to get a 9 month total cost of $327. Hope from here you are able to set up your equation now you have all the information needed :)
