### Overview

This text makes math fun, approachable, and applicable in everyday life. The authors provide algebraic modeling concepts and solutions in non-threatening, easy-to-understand language with numerous step-by-step examples to illustrate ideas. Students will discover that the practical applications of mathematical modeling will continue to be useful well after they have finished this course.

### Features and Benefits

• Concepts are presented with interesting applications for everyday use ranging from buying wallpaper to negotiating a salary package.
• The examples are presented in clear, step-by-step format to illustrate the concepts and skills being introduced.
• Calculator Mini-Lessons encourage students to become more familiar with the functions of their calculators. An Appendix that outlines the meaning and use of calculator keys is also included in the back of the book.
• Suggested laboratory exercises provide practical activities that include group and individual work.
• Extensive problem sets appear at the end of each section. The student answer key provides answers for the Chapter Reviews, Chapter Tests, and odd-numbered section exercises.
• The chapter summary includes all important terms, equations and concepts in one page.
• The Teacher's Resource Manual contains resources designed to streamline and maximize the effectiveness of your course preparation. It includes worked solutions to all of the answers in the text and a test bank with five test forms per chapter. The tests are also available online.
