Are you worth your weight in gold?
Thanks to @edrethink, @rogre, and a few others for helping me think through this one.
Pablophonic writes this about the prompt: “More importantly, I’d like to see a ransom note justified with this logic. ‘If you ever want to see your son again, assuming he’s worth his weight in gold, his current market value is $1.6 million… and dropping…’”
Pierce Presley points out this glaring error on my part: “gold is measured in troy ounces rather than the avoirdupois ones we’re used to, and that’s the unit the markets use. A Troy ounce is equal to 192/175 avoirdupois ounce, and there are 12 Troy ounces in a Troy pound. So a 200 lb. person would overvalue themselves by $566,666.67 if they failed to convert Troy ounces to avoirdupois ounces. Also, gold is in a bit of a slump lately and is just over $1,500 per Troy ounce right now.”
