Answer: The percentage change is 21.84%.
Let's see how we can calculate this percentage: what is the percentage increase/decrease from 664 to 809? Here is a very simple step-by-step guide to find out.
Step 1: We use the following formula:
\(\text{Percentage change}\) = \({Y-X \over X} \cdot 100\%\)
• \(X = 664\)
• \(Y = 809\)
• Percentage change calculation = \({809-664 \over 664}\) = \({145 \over 664}\) = \(0.2183734939759\)
• \(X = 664\)
• \(Y = 809\)
• Percentage change calculation = \({809-664 \over 664}\) = \({145 \over 664}\) = \(0.2183734939759\)
Step 2: A percentage is a number or ratio expressed as a fraction of 100.
\(0.2184\) = \(21.84 \over 100 \) = \(21.84\%\)
\(Answer: \) The percentage change is 21.84%.
\(Answer: \) The percentage change is 21.84%.
