Answer: $314,500
Step-by-step explanation:
When calculating how much of a material of any sort was used, the following formula should be used,
= Beginning inventory + Purchases - Ending inventory
This is the same formula largely used to calculate Cost of Goods sold.
Here, the figure to be concerned about is the actual materials used not the ones paid for.
Plugging in figures into the formula then,
= 3,000 + 315,000 - 3,500
= $314,500
Thus $314,500 was the inventory requisitioned for use on jobs during 2019.
