Answer: 150
By inventory, we mean a complete list of items at the end of a business day. In the case of a cook who is required to conduct a food inventory at the end of every week, inventory should include the 25 steaks in the front refrigerator and the 125 in the back freezer. The 18 marinated for tonight's dinner should not be included because it will be consumed that night. The inventory of steaks therefore is 25+125=150.
