Answer: The percentage change is 26.13%.
Let's see how we can calculate this percentage: what is the percentage increase/decrease from 80 to 100.9? Here is a very simple step-by-step guide to find out.
Step 1: We use the following formula:
\(\text{Percentage change}\) = \({Y-X \over X} \cdot 100\%\)
• \(X = 80\)
• \(Y = 100.9\)
• Percentage change calculation = \({100.9-80 \over 80}\) = \({20.9 \over 80}\) = \(0.26125\)
• \(X = 80\)
• \(Y = 100.9\)
• Percentage change calculation = \({100.9-80 \over 80}\) = \({20.9 \over 80}\) = \(0.26125\)
Step 2: A percentage is a number or ratio expressed as a fraction of 100.
\(0.2613\) = \(26.13 \over 100 \) = \(26.13\%\)
\(Answer: \) The percentage change is 26.13%.
\(Answer: \) The percentage change is 26.13%.
