Domain: geography (Route Planning and Navigation)
Problem: I’m a student at the HKUST, and in 2025 Fall semester I’m renting a place in Central to make job hunting easier. On school days, I usually take the MTR from Central to Hang Hau, then transfer to the cheapest minibus from Hang Hau to HKUST in the morning. At night, I take the shuttle bus from HKUST to Tseung Kwan O, then the MTR from Tseung Kwan O back to Central. Using the attached HKUST transportation map, please help me calculate my total commuting cost in that semester (in HKD)，assuming I pay with a student Octopus card.
