Answer: The percentage change is -20.15%.
Let's see how we can calculate this percentage: what is the percentage increase/decrease from 101 to 80.65? Here is a very simple step-by-step guide to find out.
Step 1: We use the following formula:
\(\text{Percentage change}\) = \({Y-X \over X} \cdot 100\%\)
• \(X = 101\)
• \(Y = 80.65\)
• Percentage change calculation = \({80.65-101 \over 101}\) = \({-20.35 \over 101}\) = \(-0.20148514851485\)
• \(X = 101\)
• \(Y = 80.65\)
• Percentage change calculation = \({80.65-101 \over 101}\) = \({-20.35 \over 101}\) = \(-0.20148514851485\)
Step 2: A percentage is a number or ratio expressed as a fraction of 100.
\(-0.2015\) = \(-20.15 \over 100 \) = \(-20.15\%\)
\(Answer: \) The percentage change is -20.15%.
\(Answer: \) The percentage change is -20.15%.
