Answer:
The answer is: A) malt only
Explanation:
If the manager decides to produce 400 bottles of dark beer, he will need 3,200 oz of malt and 3,200 oz of wheat. Since he can obtain 4,800 oz of malt and 3,200 o of wheat per week, at the end of the week he will have 1,600 oz of malt left in inventory (4,800 - 3,200).
