APPRECIATION

First of all, I would like to thank God for giving us energy, strength and health to carry out this project work. Next, I would like to thank our school for giving us the chance to create this project work. School also provides me the space to discuss and carry out this project work. Not forgetting my beloved parents who provided everything needed in this project work, such as money, Internet, books, computer and so on. They contribute their time and spirit on sharing their experience with me. Their support may raise the spirit in me to do this project work smoothly. After that, I would like to thank our Additional Mathematics teacher, Miss Tie Yien Mee for guiding me throughout this project. When I face some difficulties on doing tasks, she will try her best to teach me patiently until I have done the project work. Then, I would like to thank the proprietor of the shop who was willing to share their experience on business activity and the experience on saving money with me. Lastly, I would like to thank my classmates who shared ideas and providing some helps on solving problems. We help each other until we finished this project work.

OBJECTIVES

All of our students in 5I are required to carry out an Additional Mathematics Project Work during mid-term holiday. This project is done individually. Upon completion of the Additional Mathematics Project Work, I gain valuable experiences and able to: * Solve routine and non-routine problems.

* Improve thinking skills.

* Knowledge and skills are applied in meaningful ways in solving real-life problems. * Expressing ones mathematical thinking, reasoning and communication are highly encouraged and expected. * Stimulates and enhances effective learning.

* Acquire effective mathematical communication through oral and writing and to use the language of mathematics to express mathematical ideas correctly and precisely. * Enhance acquisition of mathematical knowledge and skills through problem-solving in ways that increase interest and confidence. * Prepare ourselves for the demand of our future undertakings and in workplace. * Realise that mathematics is an important and powerful tool in solving real-life problems and hence develop positive attitude towards mathematics. * Train ourselves not only to be independent learners but also to collaborate, to cooperate, and to share knowledge in an engaging and healthy environment. * Use technology especially the ICT appropriately and effectively. * Train ourselves to appreciate the intrinsic values of mathematics and to become more creative and innovative. * Realize the importance and the beauty of mathematics.

INDEX

An index number is a percentage ratio of prices, quantities or values comparing two time periods or two points in time. The time period that serves as a basis for the comparison is called the base period and the period that is compared to the base period is called the given or current period. A price index measures the change in the money value of an item (or group of items) over time whereas a quantity index measures the non-monetary value of an item (or a group of items) over time. An index number that represents a percentage comparison of the number of cars sold in a given month as compared with that of a base month is a quantity index. A price index represents a comparison of prices between two time periods and, finally, a...
