Answer:
Profit from selling at the split-off point = $13 x 1,900 units = $24,700
Profit from Processing further: = $15 x 1,900 - Processing total cost of $11,000
= $28,500 - $11,000
= $17,500
Comparison
$24,700 - $17,500
=$7,200
There is a decrease in overall profit
Conclusion: If product QI is processed further and sold, then overall profit will decrease by $7,200.
