Answer:
$47,100
Step-by-step explanation:
The cost of goods available for sale is the sum of the opening balance and the net purchases during the period.
The net purchases is the difference between the total purchases and the allowances and discounts and returns.
Hence,
Cost of goods available for sale
= $15,000 + $40,000 - $2,000 - $500 - $5,700 + $300
= $47,100
