Answer:
Holmes should sell process the product further, because the profit if process further is higher than sell product now.
Explanation:
Net profit if sell product now is $37,500 ( = sales to another manufacturer $97,500 – already spent $60,000)
Sales as in process further/ Incremental Accounting
Sales: $695,125 (=$415 x 1,675 units)
Additional Process costs: $485,570 (=$290 x 1,675 units)
Net profit if process further = total sales $695,125 – already spent $60,000 – additional process cost $485,570 = $149,555, higher than profit $37,500 if sell now.
