Solving Multi-Step Inequalities
Learning Objective

Key Concepts
Percent change is a ratio that compares the change in amounts to the original amount.
The formula for percent change is change over original = percent over 100.
To find the percent increase or decrease, first find the original amount, then find the change between the two amounts, and finally set up a proportion to solve for the percent.
