Final answer:
The inventory level for the single warehouse in Salt Lake City would be 150,000 boxes, which is calculated by adding the inventories of the three warehouses that are being consolidated.
Step-by-step explanation:
If Joe's Cookies consolidates its three warehouses in Portland, Los Angeles, and Dallas into a single warehouse in Salt Lake City, the inventory level for the single warehouse would simply be the sum of the inventories from all three existing warehouses. Since each warehouse currently holds 50,000 boxes of cookies, the calculation would be:
Portland warehouse: 50,000 boxes
Los Angeles warehouse: 50,000 boxes
Dallas warehouse: 50,000 boxes
Total inventory in Salt Lake City: 50,000 + 50,000 + 50,000 = 150,000 boxes
Therefore, the single warehouse in Salt Lake City would have an inventory level of 150,000 boxes of cookies.
