1. **Stating the problem:** We are given the sales data of two types of wood (Kayu 1 and Kayu 2) from 2019 to 2023 and asked to predict the sales trend for 2024. 2. **Data given:** - Kayu 1 sales (in thousands): 4, 8, 10, 14, 18 - Kayu 2 sales (in thousands): 4, 2, 8, 2, 6 3. **Analyzing Kayu 1 sales:** - From 2019 to 2020: increase from 4 to 8 (+4) - 2020 to 2021: increase from 8 to 10 (+2) - 2021 to 2022: increase from 10 to 14 (+4) - 2022 to 2023: increase from 14 to 18 (+4) The general trend for Kayu 1 is an increase, mostly by 4 units per year except one year with +2. 4. **Analyzing Kayu 2 sales:** - 2019 to 2020: decrease from 4 to 2 (-2) - 2020 to 2021: increase from 2 to 8 (+6) - 2021 to 2022: decrease from 8 to 2 (-6) - 2022 to 2023: increase from 2 to 6 (+4) Kayu 2 sales fluctuate up and down without a clear increasing or decreasing trend. 5. **Prediction for 2024:** - Kayu 1 is likely to continue increasing, probably by about 4 units, so expected sales around $18 + 4 = 22$ thousand units. - Kayu 2 shows fluctuating pattern but last change was an increase, so it may increase again. 6. **Answer choice evaluation:** - A: Sales equal? No, Kayu 1 is much higher. - B: Kayu 2 will increase? Likely yes. - C: Kayu 1 will decrease? No, it is increasing. - D: No change? No, Kayu 1 is increasing. - E: Kayu 1 will increase? Yes. Both B and E are plausible, but the question asks for the most precise prediction for both woods. Since Kayu 2 fluctuates, the safest is to say Kayu 1 will increase. **Final answer:** E. Kayu 1 pada tahun 2024 akan mengalami kenaikan
