Answer: The percentage change is -94.88%.
Let's see how we can calculate this percentage: what is the percentage increase/decrease from 820 to 42? Here is a very simple step-by-step guide to find out.
Step 1: We use the following formula:
\(\text{Percentage change}\) = \({Y-X \over X} \cdot 100\%\)
• \(X = 820\)
• \(Y = 42\)
• Percentage change calculation = \({42-820 \over 820}\) = \({-778 \over 820}\) = \(-0.94878048780488\)
• \(X = 820\)
• \(Y = 42\)
• Percentage change calculation = \({42-820 \over 820}\) = \({-778 \over 820}\) = \(-0.94878048780488\)
Step 2: A percentage is a number or ratio expressed as a fraction of 100.
\(-0.9488\) = \(-94.88 \over 100 \) = \(-94.88\%\)
\(Answer: \) The percentage change is -94.88%.
\(Answer: \) The percentage change is -94.88%.
