Answer: The percentage change is 291.59%.
Let's see how we can calculate this percentage: what is the percentage increase/decrease from 30.9 to 121? Here is a very simple step-by-step guide to find out.
Step 1: We use the following formula:
\(\text{Percentage change}\) = \({Y-X \over X} \cdot 100\%\)
• \(X = 30.9\)
• \(Y = 121\)
• Percentage change calculation = \({121-30.9 \over 30.9}\) = \({90.1 \over 30.9}\) = \(2.915857605178\)
• \(X = 30.9\)
• \(Y = 121\)
• Percentage change calculation = \({121-30.9 \over 30.9}\) = \({90.1 \over 30.9}\) = \(2.915857605178\)
Step 2: A percentage is a number or ratio expressed as a fraction of 100.
\(2.9159\) = \(291.59 \over 100 \) = \(291.59\%\)
\(Answer: \) The percentage change is 291.59%.
\(Answer: \) The percentage change is 291.59%.
