Products are sold in various sizes, such as 10 ounces and 20 ounces, and include a cost per unit. The cost per unit or per unit price is determined by dividing the product’s price by the number of ounces contained in the product. For example, a 20 ounce bottle of soda that sells for $3.00 cost $0.15 per ounce ($3/20 ounces=$0.15 per ounce). ................
