Answer:
B. $396.
Explanation:
The allocation of the cost to product M is shown below:
Total cost of product L would be
= 200 lbs × $8 per lb
= $1,600
Total cost of product M would be
= 150 lbs × $16 per lb
= $2,400
The total joint cost would be
= $1,600 +2,400
= $4,000
Now the cost allocated for product M would be
= Product M cost ÷ Total Joint cost × Joint cost
= $2,400 ÷ $4,000 × 660
= $396
