Answer:
The Net income will increase by $6,400
Step-by-step explanation:
Use the following formula to calculate the effect on the net income
As the fixed cost is irrelevant to special order
Net income = Increase in revenue - Increase in Variable cost - Special shipping cost
Where
Increase in revenue = 3200 x $15 = $48,000
Increase in Variable cost = 3200 x $12 = $38,400
Special shipping cost = 3200 x $1 = $3,200
Placing values in the formula
Net income = $48,000 - $38,400 - $3,200
Net income = $6,400
Hence, the net income will increase by $6,400
