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:
Bob has one more marble than Kayla.
Step-by-step explanation:
The complete question in the attached figure
Let
x -----> the number of marbles Bob has
y ----> the number of marbles Kayla has
we have
we know that
To find out how many more marbles Bob has than Kayla, subtract the number of marbles Kayla has from the number of marbles Bob has
Substitute the given values
therefore
Bob has one more marble than Kayla.

30, i don’t have the explanation i just remember this equation from Algebra 2 for some odd reason
Answer:
Mr. Meglio need to purchase 39 square feet of carpet.
Step-by-step explanation:
Given:
Total number of steps = 13
Length of each step = 1 foot
Width of each step = 3 foot
We need to find the square feet of carpet does Mr. Meglio need to purchase.
Solution:
First we will find the area of each step.
area of each step is equal to length times width.
framing in equation form we get;
area of each step =
Now amount of carpet required in square feet we multiply number of step with area of each step.
framing in equation form we get;
Amount of carpet required =
Hence Mr. Meglio need to purchase 39 square feet of carpet.
