Answer:
Product A should be processed further and then sold at $58,000.
Explanation:
In to determine this, the decision rule is to compare the revenue from selling A at the splitoff point with the net revenue from processing A further and chose the one that is greater as follows:
Revenue from selling A at the splitoff point = $40,000
Net revenue from processing A further = $58,000 - $15,000 = $43,000
Amount of increase in A revenue by processing it further = $43,000 - $40,000 = $3,000
Since the net revenue of $43,000 from processing A further is greater than the revenue of $40,000 from selling A at the splitoff point by $3,000, Product A should be processed further and then sold at $58,000.
