Answer:
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
Step-by-step explanation:
cost = $33 per month + fee
1. c(m) = 33m + f
33(6) + f = 228
198 + f = 228
f = $30 membership fee
c(m) = 33m + 30
2. at 9 months: 33(9) + 30 = $327
hopefully this helps :)
have a nice day !!
