Answer: The percentage change is -43.5%.
Let's see how we can calculate this percentage: what is the percentage increase/decrease from 90 to 50.85? Here is a very simple step-by-step guide to find out.
Step 1: We use the following formula:
\(\text{Percentage change}\) = \({Y-X \over X} \cdot 100\%\)
• \(X = 90\)
• \(Y = 50.85\)
• Percentage change calculation = \({50.85-90 \over 90}\) = \({-39.15 \over 90}\) = \(-0.435\)
• \(X = 90\)
• \(Y = 50.85\)
• Percentage change calculation = \({50.85-90 \over 90}\) = \({-39.15 \over 90}\) = \(-0.435\)
Step 2: A percentage is a number or ratio expressed as a fraction of 100.
\(-0.435\) = \(-43.5 \over 100 \) = \(-43.5\%\)
\(Answer: \) The percentage change is -43.5%.
