Answer:
The answers are:
A) 4.23 years
B) 1.08 years
C) Off course I would recommend Dave and Ellen to install these safety items, not only because they save money but also because they are very useful.
Explanation:
The cost of the deadlocks including installation is $110 for each exterior door ($220 total). The cost for installing smoke detectors is $24 for each floor ($48 total).
The discount that Dave and Ellen can get is
- $52 per year for installing the deadlocks
- $26 per year for installing the smoke detectors
A) It will take Dave and Ellen 4.23 years ($220/$52) to recover the money spent on the deadlocks.
B) It will take Dave and Ellen 1.08 years ("26/$24) to recover the money spent on the smoke detectors.
Answer:
d. Many firms are working together to eliminate pollution
Explanation:
Coase theorem is a private solution for the two parties who agree to reduce externalities, i.e., pollution. They negotiate in such a manner that the costs are low as one party takes over other party's polluted assets to reduce pollution. When there are more parties or firms involved to eliminate pollution, it will pose high transaction costs. Therefore, the Coase theorem will not work in that case. So, the option "D" is the correct choice.
Answer: increased by $20 billion
Explanation:
Real GDP is year of interest is:
= (Nominal GDP in year of interest/ GDP Price index in year of interest) * 100
= 480/120 * 100
= $400 billion
Nominal GDP is equal to Real GDP in base year so increase in real GDP is:
= 400 - 380
= $20 billion
Answer:The correct answer is a). $9,918.50
Explanation: In selling, the investor will use the bid price of $4.89 alongside the face value of the bill.
That is to say, the face value * (1-(bid price * no. of days)/days in a year) = 10000 * (1-(0.0489*60)/360) = $9,918.50
