Answer:
$146,200
Explanation:
Given that,
Raw materials inventory on January 1, 20x8 = $34,200
Raw materials inventory on December 31, 20x8 = $28,400
Raw materials used during the year = $152,000
Raw material consumed = Opening + Materials purchased - Closing stock
$152,000 = $34,200 + Materials purchased - $28,400
$152,000 - $34,200 + $28,400 = Materials purchased
$146,200 = Materials purchased
Therefore, the amount of raw materials purchased during the year is $146,200.
