Part of a series offering an approach to the world of business decision making, this volume focuses on mathematical aspects. The series is designed to cover the requirements of the Cambridge and AEB A level business studies syllabuses. The core subjects are contained in five books and there is an answer guide for the case studies book. Each volume in the series provides an analysis of the problems and behaviour within organizations. The materials used to explore key concepts and principles have been drawn from various areas of business activity: the public and private sectors; industrial and commercial organizations; and non-profit making institutions. The accompanying teacher's guides introduce topic areas, clarify objectives and suggest approaches to using the materials and to tackling various themes.
