Answer:
96,750 units.
Step-by-step explanation:
Alta Vista Company plans to sell 90,000 units in June.
Ending inventory in May equals to 15% of the next month's sale (90,000)
Inventory having may ending = 15% × 90,000
= 0.15 × 90,000
= 13,500
Inventory required to produce in June month
= 90,000 - 13,500 + 15% of July month sales
= 76,500 + 15% × 135,000
= 76,500 + 20,250
= 96,750
96,750 units should be produced in June.
