Problem $11-70($Algo$)$ Net Realizable Value of Joint Products $($LO $11-3)$

Douglass Minerals mines ore and then processes it into other products. At the end of the mining process, the ore splits off into three products: Metal$-$A$,$ Metal$-$B$,$ and Metal$-$C$.$ Douglass sells Metal$-$C at the split$-$off point, with no further processing. Metal$-$A is processed in Plant A$,$ and Metal$-$B is processed in Plant B$.$ The following is a summary of costs and other related data for the period ended December $31$:

Douglass Minerals had no beginning inventories on hand at the beginning of the period. Douglass Minerals uses the net realizable value method to allocate joint costs.

Required:

Compute the following:

a$.$ The net realizable value of Metal$-$C for the period ended December $31.$

b$.$ The joint costs for the period ended December $31$ to be allocated.

c$.$ The cost of Metal$-$B sold for the period ended December $31.$

Note: Do not round intermediate calculations. Round your final answer to the nearest whole dollar.

d$.$ The value of the ending inventory for Metal$-$C$.$

Note: Do not round intermediate calculations. Round your final answer to the nearest whole dollar.
