What is the percent of change from 80 to 20? Choices: (A)60% decrease (B)60% increase (C)75% increase (D)75% decrease

Calculate Difference: Calculate the difference between the initial and final values. Initial value: 80 Final value: 20 Difference = Final value - Initial value = 20 - 80 = -60Calculate Percent of Change: Calculate the percent of change based on the original amount. Original amount: 80 Percent of change = (Difference / Original amount) × 100% Percent of change = (-60 / 80) × 100% = -75%Determine Increase or Decrease: Determine if the percent of change is an increase or decrease.
