Problem: This is a photo I took on December 1st, 2025, when I was eating at a beef brisket noodle restaurant. The item I circled in the picture is the bowl of noodles I ordered, and besides what's shown in the image, I also ordered a drink that cost 10 HKD. Could you help me calculate how much I paid in total in RMB, based on the exchange rate on that day?
Answer: 54.6
