Answer:
Step-by-step explanation:
Given that price, p, and quantity, x, are inearly related
We are given two points on this line as (p,x) = (96.90, 121) and (40.20,310)
Using two point formula we find linear equation as

a)
is the linear equation
b) A(x)
Substitute to get
189(50.70)+56.70x = 25174.80
x=275 units
c) This is linear function hence no local maxima or minima
d) No maximia or minima
