Answer:
Colortrigon's income will increase by $30,000 if the order is accepted.
Step-by-step explanation:
Revenue = $15 per box x 6,000 boxes = $90,000
minus direct materials = $6 per box x 6,000 boxes = ($36,000)
minus direct labor = $2 per box x 6,000 boxes = ($12,000)
minus variable overhead = $2 per box x 6,000 boxes = ($12,000)
increase / decrease originated from special order = $90,000 - $36,000 - $12,000 - $12,000 = $30,000
Fixed costs are not included in calculating differential revenue from special orders.
