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:

n = 1 * 2 * 3! * 3! * 4!

Evaluate the product

n = 1728

Hence, there are 1728 possible sitting arrangements

Just Peachy Orchard produced 1100 bushels of peaches last year. This year the owner earned $8800 from sales. He's thinking that
Slav-nsk [51]

Answer:

P(t) ={8*(1.01)^t}

Step-by-step explanation:

The number of bushels produced is given by:

B(t)= 1100(1.1)^t

The owner's income is given by:

S(t) = 8800(1.111)^t

Income is given by the price per unit multiplied by the number of units sold. Therefore, the price function can be represented as:

P(t) =\frac{S(t)}{B(t)} \\P(t) =\frac{8800(1.111)^t}{1100(1.1)^t} \\P(t) =\frac{8*1100(1.1)^t*(1.01)^t}{1100(1.1)^t}\\P(t) ={8*(1.01)^t}
