First lets create an equation for each:
1) Cost = 5x + 60
2) Cost = 11x
Where x is the number of lessons.
Since we want to find the value of x (the number of lessons), we can set both equations equal to each other:
5x + 60 = 11x
Subtract 5x from both sides:
60 = 6x
Divide by 6:
x = 10
So it will take 10 lessons till a member and a nonmember pay the same amount.

A= P(1 + r)^n
where,
A= final balance
P= initial quantity
n= number of compounding periods
r= percentage interest rate
So,
P= $200
n= 6 years
r= 6%= 0.06
=$200(1 + 0.06)^6
<span>=$283.70</span>
