Answer: The percentage change is 371.43%.
Let's see how we can calculate this percentage: what is the percentage increase/decrease from 21 to 99? Here is a very simple step-by-step guide to find out.
Step 1: We use the following formula:
\(\text{Percentage change}\) = \({Y-X \over X} \cdot 100\%\)
• \(X = 21\)
• \(Y = 99\)
• Percentage change calculation = \({99-21 \over 21}\) = \({78 \over 21}\) = \(3.7142857142857\)
• \(X = 21\)
• \(Y = 99\)
• Percentage change calculation = \({99-21 \over 21}\) = \({78 \over 21}\) = \(3.7142857142857\)
Step 2: A percentage is a number or ratio expressed as a fraction of 100.
\(3.7143\) = \(371.43 \over 100 \) = \(371.43\%\)
