Answer: The percentage change is -66.45%.
Let's see how we can calculate this percentage: what is the percentage increase/decrease from 515 to 172.8? Here is a very simple step-by-step guide to find out.
Step 1: We use the following formula:
\(\text{Percentage change}\) = \({Y-X \over X} \cdot 100\%\)
• \(X = 515\)
• \(Y = 172.8\)
• Percentage change calculation = \({172.8-515 \over 515}\) = \({-342.2 \over 515}\) = \(-0.66446601941748\)
• \(X = 515\)
• \(Y = 172.8\)
• Percentage change calculation = \({172.8-515 \over 515}\) = \({-342.2 \over 515}\) = \(-0.66446601941748\)
Step 2: A percentage is a number or ratio expressed as a fraction of 100.
\(-0.6645\) = \(-66.45 \over 100 \) = \(-66.45\%\)
\(Answer: \) The percentage change is -66.45%.
