Applications of Percents Section 6.6

Objectives Solve applications involving percent Find percent of increase and percent of decrease Read data from a circle graph or construct a circle graph from data

Objective 1: Solve applications involving percent

Objective 1 “What percent of what is what?” Use percent formula or proportion to solve

Objective 2: Find percent of increase and percent of decrease

Objective 2 R = A ÷ B B is the starting number A is the amount of increase or decrease Called “percent of increase” or “percent of decrease”

Objective 3: Read data from a circle graph or construct a circle graph from data

Objective 3 Circle graph – sometimes called pie chart Shows how a whole unit is divided into parts Percents are often used as unit of measure

Objective 3 To construct circle graphs: –Find fraction or percent of each subdivision compared to total –Draw circle and divide accordingly –Circle graph – sometimes called pie chart
