Final answer:
The total quantity of raw material that the company should purchase during the year is 10,000 grams.
Step-by-step explanation:
The total quantity of raw material that Sartain Corporation should purchase during the year can be determined by calculating the difference between the beginning and ending raw material inventory. Let's assume the beginning raw material inventory is 1,430,000 grams and the ending inventory is 1,440,000 grams. Therefore, the company should purchase (1,440,000 grams - 1,430,000 grams) = 10,000 grams of raw material during the year.
In this case, the correct answer choice would be option D, 1,440,000 grams.
