Understanding Growth and Decay Factors

The video tutorial explains how to determine growth or decay factors from given percentage rates. It covers converting percentages to decimals and using these decimals to calculate growth or decay factors. The tutorial provides examples for both growth and decay scenarios, demonstrating the use of addition for growth and subtraction for decay. The video concludes with a reminder about available resources.

What is the first step in finding the growth or decay factor from a percentage rate?

• Multiply the percentage by 100

• Convert the percentage to a decimal

• Add 1 to the percentage

• Subtract the percentage from 1

When calculating a growth factor, which operation is used with the rate?

• Subtraction

• Multiplication

• Addition

• Division
