Split Company produces three products $-x,Y,$ and $Z-$ from a joint process. Each product may be sold at the split$-$off point or processed further. Additional processing requires no special facilities, and production costs of further processing are entirely variable and traceable to the products involved. Last year all three products were processed beyond split$-$off. Joint production costs for the year were $$150,000.$ Sales values and costs needed to evaluate Split's production policy follow.
