When the price rises from $1 to $2 a dvd, what is the price elasticity of demand? nothing (use the point elasticity formula at the initial price of $1. enter your response as a decimal rounded to two places.)

0.33 (to 2 decimal places)

Explanation:

Old Price =1

New Price =2

1st QDemand =150

2nd QDemand =100

Calculating the Change in Quantity Demanded

[1st QDemand - 2nd QDemand] / 2nd QDemand

[100 - 150] / 150 = (-50/150) = -1/3 = -0.3 recurring.

Calculating the Change in Price [New Price - Old Price] / Old Price

[2 - 1] / 1 = (1/1) = 1

PEoD = (% Change in Quantity Demanded)/(% Change in Price)

PEoD = -0.333/1 = -0.333 (2dp)

Ignore the negative sign when calculating price elasticity, becasue PEoD, Price Elasticity of Demand is always positive.

As PEoD = +0.33 (2dp) is less than 1, Demand is therefore Price Inelastic.

(Since Demand is not sensitive to changes in price)

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.
