Answer:
a. $ 25,300
Step-by-step explanation:
The amount of purchases can be determined by taking the cost of direct materials used in production as adjusted by the inventory movement
so the total purchases is:
Purchases = Closing Inventory + Material used - Opening inventory
$ 16,500 + $ 22,000 - $ 13,200 = $ 25,300
This can also be explained by the change in inventory values i.e $ 3,300 plus the materials used in production $ 22,000
