Answer: The percentage change is -18.72%.
Let's see how we can calculate this percentage: what is the percentage increase/decrease from 209.15 to 170? Here is a very simple step-by-step guide to find out.
Step 1: We use the following formula:
\(\text{Percentage change}\) = \({Y-X \over X} \cdot 100\%\)
• \(X = 209.15\)
• \(Y = 170\)
• Percentage change calculation = \({170-209.15 \over 209.15}\) = \({-39.15 \over 209.15}\) = \(-0.18718622997848\)
• \(X = 209.15\)
• \(Y = 170\)
• Percentage change calculation = \({170-209.15 \over 209.15}\) = \({-39.15 \over 209.15}\) = \(-0.18718622997848\)
Step 2: A percentage is a number or ratio expressed as a fraction of 100.
\(-0.1872\) = \(-18.72 \over 100 \) = \(-18.72\%\)
\(Answer: \) The percentage change is -18.72%.
\(Answer: \) The percentage change is -18.72%.
