Hot dogs are sold by the pound. some are 8 to 1 , 4 to 1, or 10 to 1, meaning there are that many hot dogs in one pound. if you have a pack of 10 to 1 hot dogs and want to sell them at a fundraiser and the cost you $3.60 per pound, how much should you charge for hot dog if you want to have a food cost of 30%.
