Answer: a. $295.81.
Step-by-step explanation:
Using the value basis would mean that the product's share of the total market value will be used to determine it's share of the cost.
Total Market Value = Product L Market Value + Product M Market Value
= (310 lbs * 10.2) + ( 260 lbs * 20.4)
= 3,162 + 5,304
= $8,466
Product L's share of total market value
= 3,162/8,466
Product L's share of the $792 based on share of total market value
= (3,162/8,466) * 792
= $295.8072
= $295.81
