A hardware store owner purchased 144 (a gross) identically priced hammers from a wholesaler. When the owner wanted to set his selling price, he checked the shop's record for the wholesale price. His accountant had written $1,#25.4# The #'s represent smudged numbers which may or may not be the same, determine the wholesale cost and the price of a single hammer.
