Answer: The percentage change is -89.4%.
Let's see how we can calculate this percentage: what is the percentage increase/decrease from 840 to 89? Here is a very simple step-by-step guide to find out.
Step 1: We use the following formula:
\(\text{Percentage change}\) = \({Y-X \over X} \cdot 100\%\)
• \(X = 840\)
• \(Y = 89\)
• Percentage change calculation = \({89-840 \over 840}\) = \({-751 \over 840}\) = \(-0.89404761904762\)
• \(X = 840\)
• \(Y = 89\)
• Percentage change calculation = \({89-840 \over 840}\) = \({-751 \over 840}\) = \(-0.89404761904762\)
Step 2: A percentage is a number or ratio expressed as a fraction of 100.
\(-0.894\) = \(-89.4 \over 100 \) = \(-89.4\%\)
\(Answer: \) The percentage change is -89.4%.
