Answer:
In July, 500 watches should be produced.
Step-by-step explanation:
The production requirement in a certain month should be such that it meets the remaining sales requirements for that month after accounting for sales that will be covered by the opening inventory and considering the budgeted sales for the next month and producing enough closing inventory as to meet the policy requirement of 50% of next month's sales.
The closing inventory required for July is,
Closing Inventory - July = 50% of August budgeted sales
Closing Inventory - July = 0.5 * 600 = 300 units
The production requirement for the period can be calculated as,
Production = Closing Inventory + Sales - Opening Inventory
Production = 300 + 400 - 200
Production = 500 units
