what is the elasticity of supply in the market for gadgets?
a.)1.2
b.).80
c.).833
d.)1.0

Respuesta :

Answer:

Option (a) is correct.

Explanation:

Average of quantity supplied:

= (70,000 + 30,000) ÷ 2

= 50,000

Percentage change in quantity supplied:

= (70,000 - 30,000) ÷ 50,000

= 0.8

Average of price change:

= (8 + 4) ÷ 2

= 6

Percentage change in price:

= (8 - 4) ÷ 6

= 0.667

Therefore,

Elasticity of supply in the market for gadgets:

= Percentage change in quantity supplied ÷ Percentage change in price

= 0.8 ÷ 0.667

= 1.2
