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
Answer: 2 1/2 hours
Step-by-step explanation: 45/18 = 2 1/2
Answer:
Step-by-step explanation:
38=2(5)+2(x ) find X
2x5-10
38-10=28
28/2=14
14/2=7
x =7
so you length is 7
Answer:
is it 8x
i'm not sure
Step-by-step explanation:
Answer:
Line A
Explanation:
Both lines have different patterns, but they both show that the amount of gallons of water increases as time increases. Line A moves more differently than line B. Line A shows an increase in that water is filling up quicker than line B. If you were to put points on a graph for both lines, you would figure out that the container for line A is filling up more quickly than the container in line B.
