Answer: The percentage change is 91.05%.
Let's see how we can calculate this percentage: what is the percentage increase/decrease from 257 to 491? Here is a very simple step-by-step guide to find out.
Step 1: We use the following formula:
\(\text{Percentage change}\) = \({Y-X \over X} \cdot 100\%\)
• \(X = 257\)
• \(Y = 491\)
• Percentage change calculation = \({491-257 \over 257}\) = \({234 \over 257}\) = \(0.91050583657588\)
• \(X = 257\)
• \(Y = 491\)
• Percentage change calculation = \({491-257 \over 257}\) = \({234 \over 257}\) = \(0.91050583657588\)
Step 2: A percentage is a number or ratio expressed as a fraction of 100.
\(0.9105\) = \(91.05 \over 100 \) = \(91.05\%\)
\(Answer: \) The percentage change is 91.05%.
\(Answer: \) The percentage change is 91.05%.
