Answer:

  A = -68.75p +2906.25

Step-by-step explanation:

We can solve for m and b using the given values of A and p.

  1600 = m·19 +b

  2150 = m·11 +b

Subtracting the second equation from the first, we have ...

  -550 = 8m

  m = -550/8 = -68.75

Substituting this into the first equation gives ...

  1600 = 19·(-68.75) +b

  b = 1600 +1306.25 = 2906.25

The desired linear equation is ...

  A = -68.75p +2906.25

Additional comment

Revenue will be maximized at the price that cuts attendance to half the value when the price is 0, about $21.14.
