Answer:
The answer is "Receivers= 200, CD player= 75,  Speaker= 250
, and Combined ( bundling )= 500".
Explanation:
As a Receiver    
If the value of P = 250, purchase only by students then,  
TR = 250 × 10,000 = 2,500,000  
If the value of P = 200, buy by  both forms  
TR = 200×(60,000) = 12,000,000  
And higher TR, 
P = 200,  
For the receivers fee of P = 200  
Player CD  
Where the value of P = 150  
TR = 150 × 10,000 = 1,500,000  
If P = 75,   
TR = 75×(60,000)  
Superior TR with P = 75,  
Rapporteurs,  
If P = 100, buy both
TR = 6,000,000 
TR= 100 × (60,000)  
If P = 250, then buy only the club owner 
TR = 250 × 50,000 
TR= 12,500,000    
So taller TR with P = 250  
Then the will to pay combined  
250 + 150 + 100 = 500 For students  
For club members, 200 + 75 + 250 = 525  
So if P = 500, you buy both forms  
TR = 500 × 60,000 people  
= 30,000,000  
If only club owners buy P = 525, then  
TR = 525 ×50,000 
TR= 2,650,000
The higher TR for P is 500.
