Answer: The percentage change is 45.45%.
Let's see how we can calculate this percentage: what is the percentage increase/decrease from 55 to 80? Here is a very simple step-by-step guide to find out.
Step 1: We use the following formula:
\(\text{Percentage change}\) = \({Y-X \over X} \cdot 100\%\)
• \(X = 55\)
• \(Y = 80\)
• Percentage change calculation = \({80-55 \over 55}\) = \({25 \over 55}\) = \(0.45454545454545\)
• \(X = 55\)
• \(Y = 80\)
• Percentage change calculation = \({80-55 \over 55}\) = \({25 \over 55}\) = \(0.45454545454545\)
Step 2: A percentage is a number or ratio expressed as a fraction of 100.
\(0.4545\) = \(45.45 \over 100 \) = \(45.45\%\)
