1. **Stating the problem:** Aqiela travels 7 km to school using an online motorcycle taxi (ojek). We need to find the total round-trip cost (to school and back) based on the given tariff table for passenger delivery. 2. **Understanding the tariff for passenger delivery:** From the table: - 1 km costs 8000 - 2 km costs 11000 - 3 km costs 14000 - 4 km costs 17000 We observe the cost increases by 3000 per km after 1 km. 3. **Finding the cost for 7 km one way:** We can find the cost for 7 km by extending the pattern: Cost at 1 km = 8000 Cost increases by 3000 per km for each additional km. So, cost for 7 km = 8000 + 3000 \times (7 - 1) = 8000 + 3000 \times 6 = 8000 + 18000 = 26000 4. **Calculating round-trip cost:** Round-trip means going to school and back, so multiply by 2: Total cost = 26000 \times 2 = 52000 5. **Answer:** The total cost for Aqiela's round trip is Rp52000, which corresponds to option D. --- **Slug:** tarif-ojek **Subject:** algebra **Desmos:** {"latex":"y=3000x+5000","features":{"intercepts":true,"extrema":true}} **q_count:** 2
