Percent Increase Then Decrease Trap

A $100 jacket price rises 20% to $120, then that new price falls 20%, landing at $96, not back to $100. The animation walks through each step with clear multiplication and subtraction: 100 x 1.20 = 120, then 120 x 0.20 = 24 subtracted to get 96. It visually proves percentages apply to the current value, a common ASVAB Arithmetic Reasoning trap, helping students avoid assuming equal percent changes cancel out.
