Answer:
The journal entry for this transaction is as follows:
Raw material Inventory A/c Dr. $72,000
To Direct material cost variance $28,200
To Accounts payable $43800
(To record the raw material transaction)
Workings:
Standard cost of Actual quantity purchased:
= Actual Quantity purchased × Standard price
= 15,000 × $3
= $45,000
Material Price variance:
= Standard cost of actual material purchased - Actual material cost
= $45,000 - $42,600
= $2,400
As the Price variance is favorable it shall be credited to Direct material cost variance.
