..... (1)
Total cost for 18 months can be represented as

Here, we have 2 equations and 2 variables whose values are to be found.
Let us use elimination method to solve the equations.
Subtracting equation (1) from (2):

Therefore, the monthly dues are <em>$70</em>.
Using equation (1), we can find the value of
.

Therefore, intuition charges are <em>$2710</em>.
