John sold 18 general admission tickets and 11 VIP tickets.
Step-by-step explanation:
Given, 
Cost of each general admission = $50 
Cost of each VIP ticket = $55
Total tickets sold = 29 
Total revenue generated = $1505 
Let, 
x represent the number of general admission tickets sold 
y represent the number of VIP tickets.
x+y=29     Eqn 1
50x+55y=1505   Eqn 2 
Multiplying Eqn 1 by 50 

Subtracting Eqn 3 from Eqn 2 

Dividing both sides by 5 

Putting y=11 in Eqn 1 

John sold 18 general admission tickets and 11 VIP tickets.

Answer:
Sh. 10,920
Step-by-step explanation:
Since the sales is above sh. 100,000,his commission is (2.4+1.5) 3.9%. 
3.9% of 280,000= 10920.
Therefore, his commission is sh. 10,920
 
        
             
        
        
        
Answer.
Step-by-step explanation:
 
        
             
        
        
        
1) This is a combination, so use ⁴⁰C₂.
     ⁴⁰C₂ = 780
     There are 780 handshakes in total.
2) I got my solution by using the combinations formula. Or another way you              could do this is to add up... 39 + 38 + 37 + 36 + 35 + 34 + 33 + 32 + 31... +1.          You will end up with 780 (I did this to double check my work).
3) The quickest way to figure this out if Drake invited 1,000 people is to use the       natural numbers formula = n(n+ 1)/2.
     Plug the numbers in: 999(1000)/2 = 499,500 
     If Drake invited 1,000 people, there would be 499,500 handshakes.
