Answer:
$500,000
Explanation:
Given that:
Sales for the month = $900,000
Opening inventory = $50,000
Closing inventory = $55,000
Gross margin on sales = 45%
Cost of goods sold = 100 - gross margin = 100% - 45% = 55%
Hence,
Cost of goods sold = $900,000 × 55% = $495,000
Therefore, the purchase for the month
= Cost of goods sold + Closing inventory - Opening inventory
= $495,000 + $55,000 - $45,000
= $500,000
