Finding Percent of Change and Final Amount Percentage

The video tutorial explains how to calculate percent change and determine what percent the final amount is of the original amount using diagrams, proportions, and equations. It uses Joe's heart rate as an example to illustrate these concepts. The tutorial also clarifies that percentages can exceed 100% and provides a pie chart analogy. Each method is explained in detail, showing how to apply them to solve percent problems effectively.

What was Joe's heart rate before and after running a mile?

• 55 and 85 beats per minute

• 50 and 80 beats per minute

• 60 and 90 beats per minute

• 70 and 100 beats per minute

Which of the following is NOT a method to solve percent problems?

• Diagrams

• Proportions

• Equations

• Graphs

What is the percent increase in Joe's heart rate from 60 to 90 beats per minute?

• 50%

• 75%

• 25%

• 100%

Using proportions, what percent is 90 of 60?

• 100%

• 125%

• 150%

• 175%

In the equation method, what operation is used to isolate the variable?

• Addition

• Subtraction

• Multiplication

• Division
