Question

38. Price elasticity of demand for a product is unity. Its demand is 25 units at a price of 5 per unit. If the
price of product rises to 6 per unit, how much quantity of the product will be demanded?
​

Answer 1

Elasticity of demand = 1

original demand = 25                             original price = 5

new demand = x                                     new price = 6

change in demand = x-25                      change in demand = 1

1   =   x-25 / 1    *     5 / 25

1   =   x-25    *     1 / 5

5   =  x-25

x =30

Answer 2

Answer:

20

Q=25

P0=5,p1=6. DeltaP=p1-p0

6-5=1

DeltaQ=Q1-Q0. Q no se da

Ed=DeltaQ÷Q×P÷deltaP
