Question 1010453
There is an initiation fee to join the Wellness Center, as well as monthly dues. The total cost after 7 months' membership will be $335, and after 1 1/2 year, $830. Find both the initiation fee and the monthly dues. Setup a system of equations and solve. Label your answers. Show step by step. 
Equations:
f + (7/12)d = 335
f + (3/2)d = 830
-----
Subtract and solve for "d":
[(3/2)-(7/12)]d = 495
-----
[(36-14)/24]d = 495
(11/12)d = 495
(1/12)d = 45
---
dues = 12*45 = $540
----
Solve for "f":
f + (3/2)d = 830
f = 830-(3/2)540
fee = 830-818 = $12
