This podcast is made by Ran Chen, who holds an EA license, Insurance and Securities licenses (Series 6, 63, 65), and the CFP® designation. He is passionate about opening access to high-quality exam preparation resources and helping learners prepare more effectively for professional certification exams. In this episode you will learn: - How to correctly calculate percent change using the (New - Old) / Old formula. - Why successive percentage changes, like a 20% increase followed by a 20% decrease, do not cancel each other out and result in a net loss. - The correct order of operations for AFOQT problems that involve applying both a discount and a sales tax to an original price. - How to identify and solve the common exam trap involving a percentage increase followed by an identical percentage decrease. - A simple mnemonic, "New minus Old, over Old we're told," to remember the percent change formula under exam pressure.
