Answer: The percentage change is 306.9%.
Let's see how we can calculate this percentage: what is the percentage increase/decrease from 21 to 85.45? Here is a very simple step-by-step guide to find out.
Step 1: We use the following formula:
\(\text{Percentage change}\) = \({Y-X \over X} \cdot 100\%\)
• \(X = 21\)
• \(Y = 85.45\)
• Percentage change calculation = \({85.45-21 \over 21}\) = \({64.45 \over 21}\) = \(3.0690476190476\)
• \(X = 21\)
• \(Y = 85.45\)
• Percentage change calculation = \({85.45-21 \over 21}\) = \({64.45 \over 21}\) = \(3.0690476190476\)
Step 2: A percentage is a number or ratio expressed as a fraction of 100.
\(3.069\) = \(306.9 \over 100 \) = \(306.9\%\)
