Answer:
B) NDPFC + Indirect Taxes
Explanation:
Net domestic product (NDP) is obtained by subtracting depreciation from gross domestic product (GDP), and it can be calculated at market price (NDPmp) or at factor cost (NDPfc):
- NDPmp = GDPmp – depreciation
- NDPfc = GDPmp – depreciation – indirect taxes
If we substitute NDPfc into option B, we will get:
NDPmp = NDPfc + indirect taxes
NDPmp = (GDPmp - depreciation - indirect taxes) + indirect taxes
NDPmp = GDPmp - depreciation 
 
        
             
        
        
        
Answer:
First Airplane Payback Period = 3 years
Second Airplane Payback Period = 4 years
Since, First Airplane is going to repay the Original Cost of the Airplane in shorter amount of time as compared to Second Airplane. Therefore, if the the decision is based on the payback approach the North should accept First Airplane.
Explanation:
NORTH AIRLINE COMPANY
<u>First Airplane:</u>                 
Payback Period = Original Cost of the Asset / Annual Cash Inflow
Payback Period = $12,000,000 / $4,000,000
Payback Period = 3 years
<u>Second Airplane:</u>
Payback Period = Original Cost of the Asset / Annual Cash Inflow
Payback Period = $24,000,000 / $6,000,000
Payback Period = 4 years
 
        
                    
             
        
        
        
-3x-5y=-15
-3x-3y=-3
-2y=-12
y=6
-3x-5(6)=-15
-3x-30=-15
-3x=15
x=-5
The answer would be C, (-5,6)
