Answer: 70% is shaded. 7 are shaded and there is a total of 10. then you divide the answer would be 0.7 which is the same as 70%

Answer:
Demand is Elastic when Price > 200 ; Demand is inelastic when Price < 200 
Step-by-step explanation:
p = 400 - 4x 
4x = 400 - p 
x = (400 - p) / 4 → x = 100 - p/4 
Elasticity of demand  [ P ed ] = (Δx / Δp) x (p / x)
Δx / Δp  [Differentiating x w.r.t p]  = 0 - 1/4  → = -1/4 
P ed =  <u>-1</u> x<u> p </u>
             4   (400 - p)/4 
= <u>-1</u> x <u> 4p </u>              = -p / (400-p) 
   4   (400 - p)
Price Elasticity of demand : only magnitude is considered, negative sign is ignored (due to negative price demand relationship as per law of demand). 
So, Ped = p / (400 - p) 
Demand is Elastic when P.ed > 1 
p / (400-p)  > 1 
p > 400 - p 
p + p > 400  → 2p > 400 
p > 400 / 2 →  p > 200 
Demand is inelastic when P.ed < 1 
p / (400-p)  < 1 
p < 400 - p 
p + p < 400  → 2p < 400 
p < 400 / 2 →  p < 200
