<h3>What is an equation?</h3>

An equation is an expression that shows the relationship between two numbers and variables.

The standard form of a linear equation is:

y = mx + b

Where m is the rate of change and b is the y intercept

Let y represent the total cost of dues over x months, hence given that:

y = 3x - 5     (1)

Also:

4x - 3y = 5

y = (4x - 5)/3      (2)

For the membership of both clubs to be the same:

3x - 5 = (4x - 5)/3    

9x - 15 = 4x - 5

x = 2

It would take 2 months for the membership of both clubs to be the same

The future value annuity is given by:
FV=(1+r)*p{[(1+r)^n-1]/r}
our value will be:
FV=(1+0.071/2)*450{[(1+0.071/2)^(9*2)-1]/0.071/2}
FV=11,468.337

The present value of the annuity will be:
FV=PV(1+r)^n
11,468.337=PV(1+0.071)^9
solving for PV we get
PV=6185.791

Answer: PV=$6185.791
