Answer: The percentage change is -73.86%.
Let's see how we can calculate this percentage: what is the percentage increase/decrease from 830 to 217? Here is a very simple step-by-step guide to find out.
Step 1: We use the following formula:
\(\text{Percentage change}\) = \({Y-X \over X} \cdot 100\%\)
• \(X = 830\)
• \(Y = 217\)
• Percentage change calculation = \({217-830 \over 830}\) = \({-613 \over 830}\) = \(-0.73855421686747\)
• \(X = 830\)
• \(Y = 217\)
• Percentage change calculation = \({217-830 \over 830}\) = \({-613 \over 830}\) = \(-0.73855421686747\)
Step 2: A percentage is a number or ratio expressed as a fraction of 100.
\(-0.7386\) = \(-73.86 \over 100 \) = \(-73.86\%\)
\(Answer: \) The percentage change is -73.86%.
\(Answer: \) The percentage change is -73.86%.
