Answer 1

Answer: There actually is an official unit of US currency worth 1/10 of a cent. It’s called a mill, and its symbol is ₥, like ¢ and $. But there are no coins or bills worth this amount. Gas stations use it because it makes it look like you’re paying less (and technically you are), even though it almost inevitably gets rounded up at the end of the transaction.
