## Overview

Introductory Algebra for College Students shows you how math applies to daily life and culture. Bob Blitzer uses realistic, interesting applications like the earnings of college graduates, the size of the national debt, and comparing our global population growth to our global food supply to demonstrate mathematical concepts in our world. These applications also are apparent in his reader-friendly examples, unique writing style and thought-provoking learning aids. Features like explanatory Voice Balloons and Great Question! study tips help you understand concepts more effectively. The 8th Edition updates Blitzer's hallmark applications, with more topics from pop culture, the news, and everyday life, offers abundant resources to help less-prepared students get up to speed, and much more.
