Answer:
The company's income will increase by $14,000.
Explanation:
Cost of goods sold per unit excludes fixed manufacturing cost:
($145,000 - $30,000)/10,000 = $11.5
If the special order is accepted:
Sales revenue of the special order = 4,000 x $15 = $60,000
Cost of good sold of the special order = 4,000 x $11.5 = $46,000
Fixed manufacturing cost does not change after the special order is accepted.
Income from the special order = $60,000 - $46,000 = $14,000
The company's income will increase by $14,000.
