Answer: The percentage change is -8.69%.
Let's see how we can calculate this percentage: what is the percentage increase/decrease from 909 to 830? Here is a very simple step-by-step guide to find out.
Step 1: We use the following formula:
\(\text{Percentage change}\) = \({Y-X \over X} \cdot 100\%\)
• \(X = 909\)
• \(Y = 830\)
• Percentage change calculation = \({830-909 \over 909}\) = \({-79 \over 909}\) = \(-0.086908690869087\)
• \(X = 909\)
• \(Y = 830\)
• Percentage change calculation = \({830-909 \over 909}\) = \({-79 \over 909}\) = \(-0.086908690869087\)
Step 2: A percentage is a number or ratio expressed as a fraction of 100.
\(-0.0869\) = \(-8.69 \over 100 \) = \(-8.69\%\)
