# Mathematically Analysing Mobile Phone Tariffs.

Extracts from this document...

Introduction

## Mobile Phones

I am investigating 3 rates of charges for people using mobile phones.

Scheme 1: A payment of £15 per month for the line rental, plus 50p per minute for each call made

Scheme 2: A payment of £24 per month for the line rental, plus 20p per minute for each call made

Scheme 3: A payment of £31 per month for the line rental, plus 10p per minute for each call made.

I am going to investigate which scheme is best for people using mobile phones.

I will also vary the line rental, vary the cost of each call, make comparisons, and make generalisations.

Conclusion

So there is no real best scheme for people to use, it depends on who the person is and how often and long they will use the mobile phone in a month. The 3 schemes could be used for a family who has 4 members. Scheme 1 would be ideal for there kids who would just need it for the quick call to get picked up from school, scheme 2 would maybe suite the mother because she would want it to keep in contact with her kids and her husband, and scheme 3 mite benefit the husband who could use it for keeping in contact with his family and also to use it for clients at work.
