A study finds that the noise from airplanes is harmful; hence, the government imposes a $25 tax on the sale of every airplane. This amount accurately accounts for the external cost of the noise pollution. Before the corrective tax, airplane tickets regularly sold for $190. After the tax is in place, the market price for airplane tickets rises to $200.A study finds that the noise from airplanes is harmful; hence, the government imposes a $25 tax on the sale of every airplane.

After the tax is in place, the market price for airplane tickets rises to $200.a. Because of the tax, the number of airplane tickets sold will decrease . b. The socially optimal price of airplane tickets is $ c. The private market price is $ d. A firm selling airplane tickets receives $ after it pays the tax.

A. Decrease

B. $200

C. $190

D. $175

Explanation:

The noise from airplanes constitute a negative externality and hence tax was levied on airplane tickets. This is known as pigouvian tax.

Negative externality is when the benefits of economic activities to third parties is less than the costs.

If a tax is levied on a good or service, it makes the good or service more expensive and quantity demanded would fall as a result. So the demand for airplane tickets is expected to fall as a result of the impostion of tax.

The social optimal price of the ticket is the priceof the ticket after the impostion of tax. This is $200

The private market price is the price before the impostion of tax. This is $190

How much the firm receives after paying for tax = social optimal price - tax

$200 - $25 = $175

I hope my answer helps you

you can lose ranking 2 ways.

1) you don't have enough points due to you expending them by asking questions/your answers are deleted.

2) your brainliest's expired. this means that brainliests, once they exceed the 30 day limit, expires. this is to ensure that you continue to contribute into the community at a constant rank if you want to continue to have/exceed the rank you have right now.

if you go to profile, and click "show more information" located on the bottom left of the box with your information (on top of the questions answered, questions asked, and friends), you will be given the following information (example):

member since : 02/13/2017, 18: 11

questions answered: 9741

questions asked: 162

no. of brainliest answers: 1575

brainliest answers in last 30 days: 10

warnings: 0 view

questions/answers reported: 2637

questions/answers incorrectly reported: 64

look at the "brainliest answers in the last 30 days". this is the one that will affect your rank other than your points. again, once your brainliest expires (was earned 31+ days ago), it will not be counted.
