Answer:
All payments will be made at the end of the year by using the present value of inflows 
Step-by-step explanation:
Present Value Of Inflows = Cash Inflow × Present Value Of Discounting Factor (Rate%,Time Period)
Present Value Of Inflows =  +
 +  +
 +  +
 + 
Present Value Of Inflows = 125466.3
 
        
             
        
        
        
The elimination method is a sufficient way to solve problems. 
2x+y= 20
6x-5y=12
Add 5y to the one equation.
2x+6y= 20
6x= 12
Subtract 2x from both sides. 
6y= 20
4x= 12
Divide 6 by 20. 
y= 3.3 
Divide 4 by 12.
x= 3

Subtract 3 from both sides,

Let x = X and y - 3 = Y
Then,

So, we have shifted the origin to a point (0, 3).
This is an odd function and the graph of an odd function is symmetrical about the origin.
That is, symmetrical about X = 0, Y = 0
Symmetrical about x = 0,, y - 3 = 0
Symmetrical about x = 0, y = 3.
Hence, the graph is symmetrical about the point (0, 3).
