Answer: The percentage change is -29.74%.
Let's see how we can calculate this percentage: what is the percentage increase/decrease from 21.35 to 15? Here is a very simple step-by-step guide to find out.
Step 1: We use the following formula:
\(\text{Percentage change}\) = \({Y-X \over X} \cdot 100\%\)
• \(X = 21.35\)
• \(Y = 15\)
• Percentage change calculation = \({15-21.35 \over 21.35}\) = \({-6.35 \over 21.35}\) = \(-0.29742388758782\)
• \(X = 21.35\)
• \(Y = 15\)
• Percentage change calculation = \({15-21.35 \over 21.35}\) = \({-6.35 \over 21.35}\) = \(-0.29742388758782\)
Step 2: A percentage is a number or ratio expressed as a fraction of 100.
\(-0.2974\) = \(-29.74 \over 100 \) = \(-29.74\%\)
\(Answer: \) The percentage change is -29.74%.
\(Answer: \) The percentage change is -29.74%.
