Final answer:
The question seeks the total number of units to be produced by Young Enterprises in July, but it lacks the necessary information to calculate this figure, such as expected unit sales or inventory data.
Step-by-step explanation:
The question is asking for the calculation of the total number of units to be produced by Young Enterprises in the month of July. However, the provided information in the question is incomplete as it does not specify the expected unit sales for July or any other information related to production, inventory, or demand that could be used to calculate the production figure. Without the necessary budgeted sales figures or additional relevant data for July or preceding months, it is impossible to accurately determine the total number of units that should be produced.
