I have extra gold from the alternate way of getting starting equipment. What should I do with the extra money? [closed]

I was using the alternate way to get equipment in Chapter 5 of the PHB (D&D 5e) as a Fighter and rolled 160 GP, which I spent on Studded Leather Armor, a Longsword, the Explorer’s Pack, a Crossbow Bolt Case, a Light Crossbow, 20 Crossbow Bolts, and a Dagger, and still have 61 GP to spend on equipment. I have no idea what to do with the extra money as I’ve bought all the equipment I want. I don’t think the PHB addressed this and don’t know what the rules say. What is do the rules say on this?
