Answer: The percentage change is 7.91%.
Let's see how we can calculate this percentage: what is the percentage increase/decrease from 27.8 to 30? Here is a very simple step-by-step guide to find out.
Step 1: We use the following formula:
\(\text{Percentage change}\) = \({Y-X \over X} \cdot 100\%\)
• \(X = 27.8\)
• \(Y = 30\)
• Percentage change calculation = \({30-27.8 \over 27.8}\) = \({2.2 \over 27.8}\) = \(0.079136690647482\)
• \(X = 27.8\)
• \(Y = 30\)
• Percentage change calculation = \({30-27.8 \over 27.8}\) = \({2.2 \over 27.8}\) = \(0.079136690647482\)
Step 2: A percentage is a number or ratio expressed as a fraction of 100.
\(0.0791\) = \(7.91 \over 100 \) = \(7.91\%\)
\(Answer: \) The percentage change is 7.91%.
\(Answer: \) The percentage change is 7.91%.
