Accepted Answer

A)  0.22. 
B)  0.88. 
C)  1.00. 
D)  1.16.
The change in quantity is (60 - 50)/(60 + 50)= 0.091 and the change in price is (5 - 6)/(5 + 6)= 0.091.Thus,elasticity is 0.091/0.091 = 1.0. 
A)  0.22. 
B)  0.88. 
C)  1.00. 
D)  1.16.
The change in quantity is (60 - 50)/(60 + 50)= 0.091 and the change in price is (5 - 6)/(5 + 6)= 0.091.Thus,elasticity is 0.091/0.091 = 1.0.

Accepted Answer

A)  0.22. 
B)  0.88.

D)  1.22.
The change in quantity is (50 - 40)/(50 + 40)= 0.111 and the change in price is (6 - 5)/(6 + 5)= 0.091.Thus elasticity is 0.111/0.091 = 1.22. 
A)  0.22. 
B)  0.88. 
C)  1.00. 
D)  1.22.
The change in quantity is (50 - 40)/(50 + 40)= 0.111 and the change in price is (6 - 5)/(6 + 5)= 0.091.Thus elasticity is 0.111/0.091 = 1.22.
