Question 81322: Please helllllppp!
The price p and the quantity x sold of a certain product obey the demand equation:
x = -20p + 500
0 less than or equal to p which is less than or equal to 25
a) express the revenue R as a function of x
b) what is the revenue if 20 units are sold?
c) what quantity x maximizes revenue? what is the maximum revenue?
d) what price should the company charge to maximize revenue?
Thank you thank you

The price p and the quantity x sold of a certain product obey the demand equation:
x = -20p + 500
p(x)=(500-x)/20 = 25-(1/20)x
0 less than or equal to p which is less than or equal to 25
a) express the revenue R as a function of x
Revenue(x) = (price)*(quantity)
Rev(x) = (25-(1/20)x)(x
Rev(x) = 25x-(1/20)x^2
b) what is the revenue if 20 units are sold?
Rev(20) = 25*20-(1/20)20^2
Rev(20) = 500-20
Rev(20) = $480
-----------------
c) what quantity x maximizes revenue? what is the maximum revenue?
Rev(x) is a quadratic with a=-1/20, b=25
max occurs at x=-b/2a = [-25/(-2/20)] = [250]
=-------------------------
d) what price should the company charge to maximize revenue?
p(x) = 25-(1/20)x
p(250) = 25-(1/20)(250)
p(250) = 25-25/2
p(250) = $12.50
