Introduction

In this article, we will delve into the mathematical analysis of membership plans with discounts and fees. We will consider three different plans, A, B, and D, and examine the effects of a 10% discount, a continuation fee, and a yearly price increase on the total cost of membership.

Plan A: 10% Discount after 12 Months

Plan A offers a 10% discount after 12 months of membership. This means that if you sign up for plan A, you will pay the full price for the first 12 months, and then you will receive a 10% discount on the subsequent years.

Let's assume that the initial price of plan A is $100 per month. After 12 months, the price will be reduced by 10%, which means that the new price will be $90 per month.

Mathematical Representation

We can represent the cost of plan A as a function of time, t, in months. The cost function can be written as:

C_A(t) = 100 - 10t

where C_A(t) is the cost of plan A at time t.

Plan B: Continuation Fee after 12 Months

Plan B also offers a continuation fee of $305 if you have a membership for more than a year. This means that if you sign up for plan B, you will pay the full price for the first 12 months, and then you will be charged a continuation fee of $305.

Let's assume that the initial price of plan B is $150 per month. After 12 months, the price will remain the same, but you will be charged a continuation fee of $305.

Mathematical Representation

We can represent the cost of plan B as a function of time, t, in months. The cost function can be written as:

C_B(t) = 150 + 305H(t-12)

where C_B(t) is the cost of plan B at time t, and H(t-12) is the Heaviside step function, which is equal to 0 for t < 12 and 1 for t ≥ 12.

Plan D: Continuation Fee after 12 Months

Plan D also offers a continuation fee of $305 if you have a membership for more than a year. This means that if you sign up for plan D, you will pay the full price for the first 12 months, and then you will be charged a continuation fee of $305.

Let's assume that the initial price of plan D is $200 per month. After 12 months, the price will remain the same, but you will be charged a continuation fee of $305.

Mathematical Representation

We can represent the cost of plan D as a function of time, t, in months. The cost function can be written as:

C_D(t) = 200 + 305H(t-12)

where C_D(t) is the cost of plan D at time t, and H(t-12) is the Heaviside step function, which is equal to 0 for t < 12 and 1 for t ≥ 12.

Yearly Price Increase of 10%

Plan A also has a yearly price increase of 10%. This means that the price of plan A will increase by 10% every year.

Let's assume that the initial price of plan A is $100 per month. After 1 year, the price will increase by 10%, which means that the new price will be $110 per month.

Mathematical Representation

We can represent the cost of plan A with a yearly price increase as a function of time, t, in years. The cost function can be written as:

C_A(t) = 100(1 + 0.1)^t

where C_A(t) is the cost of plan A at time t.

Comparison of Plans

Now that we have analyzed the costs of each plan, let's compare them.

Plan Initial Price Discount/Fee Cost after 12 months
A $100 10% discount $90
B $150 Continuation fee of $305 $150 + $305 = $455
D $200 Continuation fee of $305 $200 + $305 = $505

As we can see, plan A offers the lowest cost after 12 months, followed by plan B, and then plan D.

Conclusion

In conclusion, we have analyzed the costs of three different membership plans, A, B, and D, with discounts and fees. We have represented the costs as functions of time and compared the plans. The results show that plan A offers the lowest cost after 12 months, followed by plan B, and then plan D.

Recommendations

Based on our analysis, we recommend plan A for those who want to save money on their membership fees. However, if you are willing to pay a continuation fee, plan B may be a better option for you.

Limitations

Our analysis assumes that the prices and fees remain constant over time. However, in reality, prices and fees may change, and our analysis may not reflect the actual costs.

Future Work

In the future, we can extend our analysis to include more plans and fees, and we can also consider the effects of inflation on the costs.

Appendix

A. Mathematical Derivations

The mathematical derivations for the cost functions are as follows:

  • C_A(t) = 100 - 10t
  • C_B(t) = 150 + 305H(t-12)
  • C_D(t) = 200 + 305H(t-12)
  • C_A(t) = 100(1 + 0.1)^t

B. Code

The code for the mathematical derivations is as follows:

import numpy as np

def C_A(t):
return 100 - 10*t


def C_B(t):
return 150 + 305*np.heaviside(t-12, 0)


def C_D(t):
return 200 + 305*np.heaviside(t-12, 0)


def C_A_yearly(t):
return 100*(1 + 0.1)**t


**Frequently Asked Questions (FAQs) about Membership Plans with Discounts and Fees**
====================================================================================

**Q: What is the difference between plan A and plan B?**
---------------------------------------------------

A: Plan A offers a 10% discount after 12 months, while plan B has a continuation fee of $305 if you have a membership for more than a year.

**Q: How does the yearly price increase of 10% affect plan A?**
---------------------------------------------------------

A: The yearly price increase of 10% means that the price of plan A will increase by 10% every year. For example, if the initial price is $100 per month, after 1 year, the price will increase to $110 per month.

**Q: What is the Heaviside step function, and how is it used in the cost functions?**
