The number of possible seats is an illustration of permutation
There are 1728 possible sitting arrangements
<h3>How to determine the number of seats</h3>
From the question, we have the following highlights:
- Chris can only take 1 seat (i.e. the central seat)
- Jo can take 2 seats (i.e. the seats adjacent the central seat)
- Alex, Barb and Dave can take 3! number of seats
- Eddie, Fred, and Gareth can take 3! number of seats on the right of Chris.
- The remaining 4 adults do not have preference, then they can seat in 4! ways
So, the number of sitting arrangement is:

Evaluate the product

Hence, there are 1728 possible sitting arrangements

Answer:
y = -2x + 6
Step-by-step explanation:
y=mx + c
m is the gradient and c is the y intercept
m = (y 2 - y 1)  / (x 2 - x 1)  = (2-4) / ( 2-1) = -2
y= -2x + c
To find c, just sub one of the coordinates into the eqn:
By using the coordinates (1,4)
4 = -2(1) + c
c = 6
Therefore, the equation is y = -2x + 6

no the firm will not do the investment. because if the firm borrows the money & invest it in the project then the return will be 6% but the cost is 8%. so it will lose 2%.  
it also should not invest his own money on the project to get get the 6% return. because he could have loan the money to someone else & get 8% return. therefore his opportunity cost of investing the money is greater than the return.
therefore he should not make the investment .
