Answer: 2,900 shovels
Step-by-step explanation:
Ending Inventory = Beginning Inventory + Total Inventory Purchased - Sales
900 = 500 + Total produced - 2,500
Total Purchased = 900 + 2,500 - 500
Total purchased = 2,900 shovels
NB; There was no beginning balance in your question so I gave a random figure of 500 units. Use the equation if the figure is different.
