Answer: The percentage change is 360.47%.
Let's see how we can calculate this percentage: what is the percentage increase/decrease from 21.5 to 99? Here is a very simple step-by-step guide to find out.
Step 1: We use the following formula:
\(\text{Percentage change}\) = \({Y-X \over X} \cdot 100\%\)
• \(X = 21.5\)
• \(Y = 99\)
• Percentage change calculation = \({99-21.5 \over 21.5}\) = \({77.5 \over 21.5}\) = \(3.6046511627907\)
• \(X = 21.5\)
• \(Y = 99\)
• Percentage change calculation = \({99-21.5 \over 21.5}\) = \({77.5 \over 21.5}\) = \(3.6046511627907\)
Step 2: A percentage is a number or ratio expressed as a fraction of 100.
\(3.6047\) = \(360.47 \over 100 \) = \(360.47\%\)
\(Answer: \) The percentage change is 360.47%.
\(Answer: \) The percentage change is 360.47%.
