x = D(p) = 200 - p

Question

need an answer

Answer 1

qiamtity demanded= x which is inversely related to price

the function is linear

x = P(x) = 100 -p

when p=100 no one buys any

if P = 0, most they buy is 100

revenue R = xp = p(100 - p) = 100p -p^2

max revenue is when R' = 0 = 100 -2p, p =50

max R = 2500
