I believe you are asking in how many ways they can sit. If so:
The 1st can sit anywhere: he has only 1 way to sit
The 2nd can sit in 11 ways, since one seat is already occupied
The 3rd can sit in 10 ways, since 2 seat are already occupied
The 4th can sit in 9 ways, since 3 seat are already occupied
The 5th can sit in 8 ways, since 4 seat are already occupied
--------------------------------------------------------------------------------
The 12th can sit in 1 way, since11 seat are already occupied
General formula for a circular table:
Number of ways they n persons can be seated: (n-1)!
and the 12 can be seated in (12-1)! = 11! = 39,916,800 ways.
This is called circular permutation
Answer:
A. $1,110
B. 50 units.
Step-by-step explanation:
A. Substitute 
into the function 
for calculate the time in hours required for the worker to produce 18 units:
Now you need to substitute 
into the function 
to calculate the amount in dollars she will be paid for 74 hours:
She will be paid $1,110.
B. To calculate the number of units that the worker needs to produce to be paid $3,030 , you need to substitute 
into the function and solve for T (to find the number of hours she requires to work to be paid $3,030)
Now, substitute 
into and solve for x, to calculate the number of units she produces in 202 hours:
She would need to produce 50 units to be paid $3,030
There is usually calculator that will solve it for you look for them just plug the question in and it can show the steps too
