1. Problem: Find the month with the highest percentage change in rice price in Kabupaten Sejahtera in 2022. 2. Formula: Percentage change between two months is calculated as $$\text{Percentage Change} = \frac{\text{Price}_{\text{current}} - \text{Price}_{\text{previous}}}{\text{Price}_{\text{previous}}} \times 100\%$$ 3. Calculate percentage changes month to month: - Feb from Jan: $\frac{10,600 - 10,800}{10,800} \times 100 = -1.85\%$ - Mar from Feb: $\frac{11,200 - 10,600}{10,600} \times 100 = 5.66\%$ - Apr from Mar: $\frac{11,100 - 11,200}{11,200} \times 100 = -0.89\%$ - May from Apr: $\frac{11,600 - 11,100}{11,100} \times 100 = 4.50\%$ - Jun from May: $\frac{11,000 - 11,600}{11,600} \times 100 = -5.17\%$ - Jul from Jun: $\frac{10,800 - 11,000}{11,000} \times 100 = -1.82\%$ - Aug from Jul: $\frac{10,800 - 10,800}{10,800} \times 100 = 0\%$ - Sep from Aug: $\frac{11,000 - 10,800}{10,800} \times 100 = 1.85\%$ - Oct from Sep: $\frac{11,100 - 11,000}{11,000} \times 100 = 0.91\%$ - Nov from Oct: $\frac{11,700 - 11,100}{11,100} \times 100 = 5.41\%$ - Dec from Nov: $\frac{11,400 - 11,700}{11,700} \times 100 = -2.56\%$ 4. Identify highest absolute percentage change: The largest magnitude is $5.66\%$ in March (increase) and $5.17\%$ in June (decrease). 5.
