Computing Joint Costs $-$ Sales Value at Split$-$Off and Net Realizable Value Methods D$.$ L$.$ Manufacturing Inc.$\text{'}$s joint cost of producing $1,000$ units of Product A$,500$ units of Product B$,$ and $500$ units of Product C is $$20,000.$ The unit sales values of the three products at the split$-$oft point are Product A$-$$$20,$ Product B$-$$$200,$ and Product C$-$$$160.$ Ending inventories include $100$ units of Product A$,200$ units of Product B$,$ and $300$ units of Product C$.$ In your interim calculations, round sales value percentages and allocated joint costs to two decimal places.

Assume that Product C can be sold for $$200$ a unit if it is processed after split$-$off at a cost of $$25$ a unit. Compute the amount of joint cost that would be included in the ending inventory valuation of the three products on the basis of their net realizable values.
