Answer:
b. $225,000
Step-by-step explanation:
The computation of the change in annual net operating income is shown below:
First we need to do following calculations
Sales of Division P is
= Sale Units × Sales Price Per Unit
= 60,000 × $100
=$6,000,000
Variable Cost is
= Sale Units × Variable Cost Per Unit
= 60,000 × $65
= $3,900,000
Now Current Operating Income is
= Sales - Variable Cost
= $6,000,000 - $3,900,000
= $2,100,000
Operating Capacity of Division P is 75,000 Units
If Division Q buy 30,000 wheel sets annually from Division P at $87 than Operating Income of Division P:-
= 75,000 - 30,000
= 45,000 Units
Sales is
= 45,000 Units × $100 + 30,000 units × $87
= $45,00,000 + $26,10,000
= $71,10,000
Variable Cost is
= 75,000 Units × $65
= $48,75,000
Post Operating Income is
= Sales - Variable Cost
= $7,110,000 - $4,875,000
= $22,35,000
Increase in Operating Income of Division P is
= Post Operating Income - Current Operating Income
= $2,235,000 - $2,100,000
= $135,000
Increase in Operating Income of Division Q is
= Sale Units × (Outside Supplier Cost Per Unit - Division P Cost Per Unit)
= 30,000 Units × ($90 - $87)
= $90,000
If Q buy the Wheel From Division P. Q saves $3 per wheel set.
Increase in Operating Income of Company is
= Increase in Operating Income of Division P + Increase in Operating Income of Division Q
= $135,000 + $90,000
= $225,000
