Answer:
1,760,000 gram
Explanation:
For computing the purchase of raw material, first we have to determine the required production which is shown below:
= Sale units + ending finished inventory units - beginning finished inventory units
= 540,000 units + 69,000 units - 19,000 units
= 590,000 units
The 3 gram is required, so the production would be
= 590,000 units × 3 gram
= 1,770,000 gram
Now the purchase of material would be
= Required production + ending raw material inventory units - beginning raw material inventory units
= 1,770,000 gram + 39,000 gram - 49,000 gram
= 1,760,000 gram
