Answer:
It is a disadvantage to continue processing QI. The lost on profit is= $5500
Explanation:
Product QI has been allocated $18,300 of the total joint costs of $39,000.
A total of 2,500 units of product QI are produced.
Product QI can be sold at the split-off point for $14 per unit.
It can be processed further for an additional total cost of $10,500 and then sold for $16 per unit.
Split-off point:
Sales= 2500q*$14=$35000
Total cost=$18300
Profit=$16700
Post-split-off:
Sales=2500*16=$40000
Cost previous split-off=$18300
Added cost= $10500
Profit=$11200
Comparing profits (16700>11200) it is not beneficial to continue processing QI products.
