Answer: The percentage change is -15.21%.
Let's see how we can calculate this percentage: what is the percentage increase/decrease from 815 to 691? Here is a very simple step-by-step guide to find out.
Step 1: We use the following formula:
\(\text{Percentage change}\) = \({Y-X \over X} \cdot 100\%\)
• \(X = 815\)
• \(Y = 691\)
• Percentage change calculation = \({691-815 \over 815}\) = \({-124 \over 815}\) = \(-0.1521472392638\)
• \(X = 815\)
• \(Y = 691\)
• Percentage change calculation = \({691-815 \over 815}\) = \({-124 \over 815}\) = \(-0.1521472392638\)
Step 2: A percentage is a number or ratio expressed as a fraction of 100.
\(-0.1521\) = \(-15.21 \over 100 \) = \(-15.21\%\)
\(Answer: \) The percentage change is -15.21%.
