Section 5.1 Percent and Change

Percent is a concept that arises in many areas of daily life. In Chapter 4,  we used percent in describing change in exponential equations. In this section, we’ll look at other ways that percents are used to describe portions of amounts (like 84.4% of all children are vaccinated against diphtheria, tetanus and pertussis) and how we can calculate the percent change in a quantity.

Our objectives are

  • To perform percent calculations.
  • To compute percent change from data.
  • To solve applied problems using percents.

Use the workbook and videos below to help you accomplish these objectives.
