Answer: The percentage change is -1.83%.
Let's see how we can calculate this percentage: what is the percentage increase/decrease from 30 to 29.45? Here is a very simple step-by-step guide to find out.
Step 1: We use the following formula:
\(\text{Percentage change}\) = \({Y-X \over X} \cdot 100\%\)
• \(X = 30\)
• \(Y = 29.45\)
• Percentage change calculation = \({29.45-30 \over 30}\) = \({-0.55 \over 30}\) = \(-0.018333333333333\)
• \(X = 30\)
• \(Y = 29.45\)
• Percentage change calculation = \({29.45-30 \over 30}\) = \({-0.55 \over 30}\) = \(-0.018333333333333\)
Step 2: A percentage is a number or ratio expressed as a fraction of 100.
\(-0.0183\) = \(-1.83 \over 100 \) = \(-1.83\%\)
\(Answer: \) The percentage change is -1.83%.
\(Answer: \) The percentage change is -1.83%.
