Suppose that the price of a money clip increases from $0.75 to $0.90 and quantity supplied rises from 8,000 units to 10,000 units. Use the midpoint formula to calculate the price elasticity of supply. 1. 1.22 2. 1.0 3. 0.82 4. 0.07

1.      1.22

Explanation:

P = Price of money clip

S = Supply of money clip

P1 = 0.75

P2 = 0.90

S1 = 8,000

S2 = 10,000

Mid point Formula = [ ( S2- S1 ) / ( P2- P1 ) ] / [ ( ( S2+ S1 ) / 2) / ( ( P2 + P1 )/2 ) ]

Price Elasticity of Supply =  [ ( 10,000- 8,000 ) / ( 0.90- 0.75 ) ] / [ ( ( 10,000+ 8,000 ) / 2) / ( ( 0.90 + 0.75 )/2 ) ]

Price Elasticity of Supply = (2,000 / 0.15) / (9,000 / 0.825)

Price Elasticity of Supply = 13,333.33 / 10909.09

Price Elasticity of Supply = 1.22
