Answer: The percentage change is 29.78%.
Let's see how we can calculate this percentage: what is the percentage increase/decrease from 638 to 828? Here is a very simple step-by-step guide to find out.
Step 1: We use the following formula:
\(\text{Percentage change}\) = \({Y-X \over X} \cdot 100\%\)
• \(X = 638\)
• \(Y = 828\)
• Percentage change calculation = \({828-638 \over 638}\) = \({190 \over 638}\) = \(0.29780564263323\)
• \(X = 638\)
• \(Y = 828\)
• Percentage change calculation = \({828-638 \over 638}\) = \({190 \over 638}\) = \(0.29780564263323\)
Step 2: A percentage is a number or ratio expressed as a fraction of 100.
\(0.2978\) = \(29.78 \over 100 \) = \(29.78\%\)
