Domain: commerce (Transaction and Price Calculation)
Problem: This is a photograph that I took on November 23, 2025. At that time, I went on this together with my parents, and the three of us rode it as a family. Unfortunately, I later lost the tickets we purchased, so I can no longer check the exact details. However, I vaguely remember that we seemed to have bought three adult tickets, although I am not entirely certain and my memory of it is a bit unclear. Could you please help me calculate how much money the three of us spent in total on the tickets?
