The demand curve for gasoline slopes downward and the supply curve for gasoline slopes upward. The production of the 200th gallon of gasoline entails the following: • a private cost of $3.03;
• a social cost of $3.23;
• a value to consumers of $3.39.
Refer to Scenario 10-1. Suppose the equilibrium quantity of gasoline is 220 gallons; that is, Q MARKET = 220. Then the equilibrium price of a gallon could be:
a. $3.08.
b.$2.77.
c. $2.45.
d. $3.69.

a. $3.08

Explanation:

Calculation to determine what the equilibrium price of a gallon could be:

Based on the information given the Private cost is $3.03 while the Social cost is $3.23 which indicates that Social cost lies ABOVE the private cost and since The MARKET EQUILIBRIUM tend to occurs when Private value=Private cost which means that the EQUILIBRIUM PRICE lies between $3.03 and $3.23, Therefore the EQUILIBRIUM PRICE of a gallon would be $3.08 because it lies between $3.03 and $3.23.

cool i use it all the time

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.
