Answer: The percentage change is -73.13%.
Let's see how we can calculate this percentage: what is the percentage increase/decrease from 30.15 to 8.1? Here is a very simple step-by-step guide to find out.
Step 1: We use the following formula:
\(\text{Percentage change}\) = \({Y-X \over X} \cdot 100\%\)
• \(X = 30.15\)
• \(Y = 8.1\)
• Percentage change calculation = \({8.1-30.15 \over 30.15}\) = \({-22.05 \over 30.15}\) = \(-0.73134328358209\)
• \(X = 30.15\)
• \(Y = 8.1\)
• Percentage change calculation = \({8.1-30.15 \over 30.15}\) = \({-22.05 \over 30.15}\) = \(-0.73134328358209\)
Step 2: A percentage is a number or ratio expressed as a fraction of 100.
\(-0.7313\) = \(-73.13 \over 100 \) = \(-73.13\%\)
\(Answer: \) The percentage change is -73.13%.
\(Answer: \) The percentage change is -73.13%.
