Answer:
Midpoint value of price elasticity of demand = -2.07
Explanation:
We know,
Midpoint value of price elasticity = ![\frac{(Q_{2} - Q_{1})/[(Q_{2} + Q_{1})/2] }{(P_{2} - P_{1})/[(P_{2} + P_{1})/2] }](https://tex.z-dn.net/?f=%5Cfrac%7B%28Q_%7B2%7D%20-%20Q_%7B1%7D%29%2F%5B%28Q_%7B2%7D%20%2B%20Q_%7B1%7D%29%2F2%5D%20%7D%7B%28P_%7B2%7D%20-%20P_%7B1%7D%29%2F%5B%28P_%7B2%7D%20%2B%20P_%7B1%7D%29%2F2%5D%20%7D)
Given,
Original Price,
= $15
New Price,
= $12
Original Quantity demanded,
= 1,000 units
New Quantity demanded,
= 1,600 units
Putting the value in the above midpoint formula, we can get
Midpoint value of price elasticity = ![\frac{(1,600 - 1,000)/[(1,600 + 1,000)/2]}{(12-15)/[(12+15)/2]}](https://tex.z-dn.net/?f=%5Cfrac%7B%281%2C600%20-%201%2C000%29%2F%5B%281%2C600%20%2B%201%2C000%29%2F2%5D%7D%7B%2812-15%29%2F%5B%2812%2B15%29%2F2%5D%7D)
Midpoint value of price elasticity = 
Midpoint value of price elasticity = 
Midpoint value of price elasticity of demand = -2.07

Answer: Social comparison
Explanation:
The social comparison is one of the important theory in the society which state that the individual person can determine their own personal and the social importance by comparing their own qualities with the other people. The coal comparison is mainly proposed by the Leon festinger in the year 1954.
According to the given scenario, the self evaluation is basically conducted by the Lori is best illustrate example of the social comparison as people generally compared themselves with the other people for the purpose of self motivation and improvement.
Therefore, Social comparison is the correct answer.
The answer is savings account A.
Since savings account A compounds the interest quarterly it adds interest to the account every quarter. This makes it a more profitable account than one that compounds the interest semiannually. The reason is that the bank is adding interest more frequently, so you are earning interest on the interest that the bank has already paid you.
The three basic question of economic is
What to produce
How to produce
For whom to produce
Therefore the answer would be
1.How will the goods and service be produced
2.How will the goods and service be produced
3.Who will consume the goods and services
