Answer:
9,800 units were produced in March
Step-by-step explanation:
Ending inventory is calculated by adding Beginning inventory in production for the year and deducting any items sold during the year.
The formula for Ending Inventory is as follow
Ending Finished Goods Inventory = Beginning Finished Goods Inventory + Production in the period - Sales Made During the period
As we have the ending Inventory we need to calculate the production during March. Placing the available amounts in the formula
1,400 units = 2,100 units + Production in the period - 10,500 units
1,400 units -2,100 units + 10,500 units = Production in the period
Production in the period = 9,800 units
