Answer: The percentage change is 290.24%.
Let's see how we can calculate this percentage: what is the percentage increase/decrease from 20.5 to 80? Here is a very simple step-by-step guide to find out.
Step 1: We use the following formula:
\(\text{Percentage change}\) = \({Y-X \over X} \cdot 100\%\)
• \(X = 20.5\)
• \(Y = 80\)
• Percentage change calculation = \({80-20.5 \over 20.5}\) = \({59.5 \over 20.5}\) = \(2.9024390243902\)
• \(X = 20.5\)
• \(Y = 80\)
• Percentage change calculation = \({80-20.5 \over 20.5}\) = \({59.5 \over 20.5}\) = \(2.9024390243902\)
Step 2: A percentage is a number or ratio expressed as a fraction of 100.
\(2.9024\) = \(290.24 \over 100 \) = \(290.24\%\)
\(Answer: \) The percentage change is 290.24%.
\(Answer: \) The percentage change is 290.24%.
