A. find the price elasticity of demand at the equilibrium points? quantity demand=72-8p and quantity supply=-24 +24p. B. substitutes the equation.​

p = 3

Step-by-step explanation:

The price elasticity of demand at the equilibrium points occurs when quantity demand equals quantity supply.

So,

72-8p= -24 +24p

Taking like terms together,

72+24 = 24p+8p

96 = 32p

p = 3

Hence, the price elasticity of demand is at p = 3.

answer

d. 10

explanation

the distance from point y to wx is the height of the triangle.

using pythagoras theorem,

group similar terms to get,

this implies that,

take positive square root of both sides to get,

this implies that,

1. 3. can also be expressed as (22/7)

2. -4.5

3. 3.6
