i.e.

For, the x coordinates.

Where




For the y coordinates:

Where




Hence:

 
        
             
        
        
        
You are correct. For each of the three possibilities for their second day, there are two possibilities for the third day. 
The total number of possibilities is 3*2 = 6.
 
        
             
        
        
        
Answer:
y = 12
Step-by-step explanation:
Use the equation y = kx
Plug in x and y to find k:
2 = k(16)
1/8 = k
Then, plug in 1/8 as k and 96 as x to find y:
y = 1/8(96)
y = 12
