Answer: The percentage change is 1850%.
Let's see how we can calculate this percentage: what is the percentage increase/decrease from 20 to 390? Here is a very simple step-by-step guide to find out.
Step 1: We use the following formula:
\(\text{Percentage change}\) = \({Y-X \over X} \cdot 100\%\)
• \(X = 20\)
• \(Y = 390\)
• Percentage change calculation = \({390-20 \over 20}\) = \({370 \over 20}\) = \(18.5\)
• \(X = 20\)
• \(Y = 390\)
• Percentage change calculation = \({390-20 \over 20}\) = \({370 \over 20}\) = \(18.5\)
Step 2: A percentage is a number or ratio expressed as a fraction of 100.
\(18.5\) = \(1850 \over 100 \) = \(1850\%\)
\(Answer: \) The percentage change is 1850%.
