Hope this helps
Because, salt was needed to flavor food, preserve meat, used for medical purposes, and to keep the body healthy. But in West Africa, salt was rare. So, West Africans traded their gold for salt. Salt was so valuable, it was worth its weight in gold. 1 pound of salt = 1 pound of gold. How amazing.
Hope it helped
