<s>[INST] I forgot the length of this wire and I need to figure out if I can use it for a project. If I know that I have a spool of wire with a weight of 2 3/4 pounds, and the spool is full when the wire has a length of 100 feet, how can I figure out the length of the wire that is left of the spool with a weight of 2 5/8 pounds?[/INST]
