Answer: The percentage change is 34.88%.
Let's see how we can calculate this percentage: what is the percentage increase/decrease from 645 to 870? Here is a very simple step-by-step guide to find out.
Step 1: We use the following formula:
\(\text{Percentage change}\) = \({Y-X \over X} \cdot 100\%\)
• \(X = 645\)
• \(Y = 870\)
• Percentage change calculation = \({870-645 \over 645}\) = \({225 \over 645}\) = \(0.34883720930233\)
• \(X = 645\)
• \(Y = 870\)
• Percentage change calculation = \({870-645 \over 645}\) = \({225 \over 645}\) = \(0.34883720930233\)
Step 2: A percentage is a number or ratio expressed as a fraction of 100.
\(0.3488\) = \(34.88 \over 100 \) = \(34.88\%\)
\(Answer: \) The percentage change is 34.88%.
