Let M be the number of units to make and B be the number of units to buy. If it costs $2 to make a unit and $3 to buy a unit and 4000 units are needed, the objective function is Min 2M + 3B

Min 4000 (M + B)

Max 2M + 3B

Max 8000M + 12000B

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.
