Answer: -0.9 ; inelastic
Explanation:
Given:
The average price of wheat per metric ton in 2012 = $305.75
Demand (in millions of metric tons) in 2012 = 672
The average price of wheat per metric ton in 2013 = $291.56
Demand (in millions of metric tons) in 2013 = 700
We will compute the elasticity using the following formula:
ε =

ε =

Now , we'll first compute

i.e.
=

= 0.04081
Similarly for

i.e.
=

= -0.0475
ε =

ε = -0.859
-0.9
we know that ;
If, ε > 1 ⇒ Elastic
ε < 1 ⇒ Inelastic
ε = 1 ⇒ unit elastic
Here , ε = -0.859
-0.9
Therefore ε is inelastic.
