Answer:
The cost of goods available for sale is $4,760
Step-by-step explanation:
Goods available for sales include all those goods which is available on the beginning of the period and all the purchases / production during the period.
Beginning Inventory = 20 x $44 = $880
Purchases for the month = ( 20 x 45 ) + ( 20 x 46 ) + ( 20 x 49 ) + ( 20 x 54 )
Purchases for the month = $900 + $920 + $980 + $1,080
Purchases for the month = $3,880
Cost of Goods available for sale = Beginning Inventory + Purchase for the month = $880 + $3,880 = $4,760
