(a) Find the demand function (price p as a function of attendance x), assuming it to be linear.

P(x)=_____

How should ticket prices be set to maximize revenue? (Round your answer to the nearest cent.)

(49 k, 10) and (51 k, 8)

slope = (8-10)/(51 k - 49 k) = -1/1k

p = -(1/k)x+ b

10 = -(1/k)49 k + b

59 = b

so

p = -(1/k)x + 59 or p = -x/1000 + 59

r = x p

r = -x^2/1000 + 59 x

x^2 -59000 x = 1000 r

x^2 - 59000 x + 29,500^2 = 1000 r + 29,500^2

(x-29,500)^2 = 1000(r + 870,250)

so max r at x = 29,500 people and revenue of 870,250

then price = 870,250/29,500 = $29.50

then p =

**Damon**, Sunday, July 15, 2012 at 6:49pmr = x p

r = -x^2/1000 + 59 x

x^2 -59000 x = -1000 r

x^2 - 59000 x + 29,500^2 = -1000 r + 29,500^2

(x-29,500)^2 = 1000(r - 870,250)

so max r at x = 29,500 people and revenue of 870,250

then price = 870,250/29,500 = $29.50
