Answer: Alternative 3 will be selected.
Explanation:
The system that should be selected is the alternative that is better than the other alternatives by being higher than MARR if selected. 
First compare A1 to A0
The rate of return here is 18% which is higher than the MARR of 15% so Alternative 1 should be chosen over A0 which is to do nothing. 
Compare A1 to A2
If A2 is chosen over A1, the incremental return is 10% which is less than the MARR of 15% so A2 should not be chosen over A1. A1 should instead be chosen over A2.
Compare A1 to A3
If A3 is chosen over A1 then the incremental return would be 18%. This is higher than the MARR of 15% so Alternative 3 should be chosen over Alternative 1.
Alternative 3 should be chosen over A1 which should be chosen over A2 and A0.
A3 will therefore be selected. 
 
        
             
        
        
        
Answer:
(a) $33750000 (b) $11250000 (c) $22500000
Explanation:
Solution
(a) How much would Ziegler Inc. total income of operating  increase.
Now,
Units * (Cost of purchased from outside supplier - Variable cost)
Thus,
75000 * ($1350 - $900) = $33750000
(b) How much would the Instrument Division's operating income increase
Now,
The Units * (Cost of purchased from outside supplier - Transfer Price)
So,
75000 units * ($1350 - $1200) = $11250000
(C) How much would the Components Division's operating income increase?
Now,
Units * (Transfer Price - Variable cost)
75000 units * ($1200 - $900) = $22500000
 
        
             
        
        
        
The percentage of 250000 to 180000 is 72% or answer D
