Jack paid $560 in fees for a certain duration of club membership dues. The admission fee of the club was $200, and Jack has to pay $30 per month to continue his membership. The function for his club fees is given.

Answer:
12 months or a year
Step-by-step explanation:
I'm guessing you need to know the duration of his membership?
560= 30x + 200
x= months
560 -200 = 360
360/30 = 12 months = 1 year
