Answer: The percentage change is -30.75%.
Let's see how we can calculate this percentage: what is the percentage increase/decrease from 80 to 55.4? Here is a very simple step-by-step guide to find out.
Step 1: We use the following formula:
\(\text{Percentage change}\) = \({Y-X \over X} \cdot 100\%\)
• \(X = 80\)
• \(Y = 55.4\)
• Percentage change calculation = \({55.4-80 \over 80}\) = \({-24.6 \over 80}\) = \(-0.3075\)
• \(X = 80\)
• \(Y = 55.4\)
• Percentage change calculation = \({55.4-80 \over 80}\) = \({-24.6 \over 80}\) = \(-0.3075\)
Step 2: A percentage is a number or ratio expressed as a fraction of 100.
\(-0.3075\) = \(-30.75 \over 100 \) = \(-30.75\%\)
\(Answer: \) The percentage change is -30.75%.
\(Answer: \) The percentage change is -30.75%.
