Answer: Marginal cost under demand and supply theory. Answer is 80
Explanation: QD 100-4P, Marginal Cost =S4,QS =6P -20. So
the calculation goes thus = QS=6p-20
Inputing Marginal value of 4 equates 100-4(4)
100-16 = 84
QS=6(4)-4
24-20=4
profit maximisation =QD-QS
84-4=80
Answer:
$30,000
Explanation:
the present value of the loan = $100,848 - $30,000 = $70,848
we can use the present value annuity formula:
PV = annual payment x PV annuity factor
annual payment = PV / PV annuity factor
PV = $70,848
PV annuity factor, 25%, 4 periods = 2.3616
annual payment = $70,848 / 2.3616 = $30,000

Explanation:
1. Racial predisposition; this research violates very basic ethical code of racial discrimination. There is no way that a researcher can be allowed to target a specific group of people based on their biological race. This type of discrimination hinders the authenticity of research and have far reaching repercussions for the target group as well as the whole society.
2. Electroshock therapy; this research’s target population is preteens and adolescents, experimenting such an extreme punishment on them has no justification. This causes direct harm to the children. Besides the electroshock are used on chronic psychic patients not on general public not even adults let alone the preteens.
3. Health Problems, Diet, and Socioeconomic Status; this research proposal is better than the previous two proposals but it has some ethical regarding the consequences of the publicly published findings. Rather it would be more effective to keep these findings to the policy makers and work for the betterment of the lower status peoples so that they can also eat healthy diet.
Answer: B. 20 fewer tons of pollution into the air, and Firm B will emit 100 fewer tons of pollution into the air.
Explanation:
If Firm B uses the pollution permits as assigned, it would have to spend $6000 for pollution elimination (60 tons, $100 each). If Firm A uses only the pollution permits assigned, it would have to spend $12000 for pollution elimination (60 tons, $200 each).
However, if firm B sells all 40 permits to firm A, as long as the value of each permit is higher than $100 and lower than $200, firm B could make a profit, and firm A could save money.
In that case, firm A could emit 80 tons of pollution into the air, and firm b could avoid emitting any pollution.
