If the price of a haircut is $15, the number of haircuts provided is 100. If the price rises to $30 per haircut, barbers will work much longer hours, and the supply of haircuts will increase to 300. Instructions: Round your answers to two decimal places.
The price elasticity of supply for haircuts between $15 and $30 using the mid-point method is:.

1.5

Explanation:

Price elasticity of supply measures the responsiveness of quantity supplied to changes in price of the good.

Price elasticity of supply = midpoint change in quantity supplied / midpoint change in price  

Midpoint change in quantity supplied = change in quantity supplied / average of both supply

change in quantity supplied = 300 - 100 = 200

average of both supply = (300 + 100) / 2 = 200

200 / 200 = 1

midpoint change in price = change in price / average of both price

change in price = $30 - $15 = $15

average of both price = ($30 + $15) / 2 = $22.50

15 / 22.5 = 0.67

1 / 0.67 = 1.5

If the absolute value of price elasticity is greater than one, it means supply is elastic. Elastic supply means that quantity supplied is sensitive to price changes.  

answer: b) the us is the leading importer but not the leading exporter.

extra info:

the u.s is the largest importer but it is not the largest exporter as china sits on the top of the table when it comes to leading exporters.

but u.s is not far from first,

they rank in 2nd globally as the worlds largest exporter.
