Answer:
Min 2M + 3B
Explanation:
Data provided in the question
Let us assume M denotes the making units
B denotes the buying units
So,
Making cost per unit = $2
And, the buying cost per unit = $3
And, the total number of units required = 4,000 units
Based on the above information, the objective function is Min 2M + 3B.
This indicates the minimum total cost
Hence, the correct option is A.
