Answer:
Purchases in August = $30000
Explanation:
Cost of golds sold = opening inventory + purchases - closing inventory
Purchase therefore would be
Purchases = cost of goods sold(COS) + closing inventory - opening inventory
Opening inventory in August = Closing inventory for July i.e (20%× august):
= 20% × 28,000 = 5600
Closing inventory in August = 20%× September COS
= 20%× 38,000 = 7600
Purchases in August
= 28,000+7600 - 5600
= $30000
