Answer:
A) The mower is only expected to be needed for three years.
Explanation:
Excelsior is surely more expensive than the Grassassinator, due to its longer working life. Therefore, it is essential to examine the period of use of the lawn mower. There is absolutely no need to invest in a long-running lawn mower if it is going to be needed twice less the time. In this case, it would be more financially efficient to invest in the Grassassinator.
Answer: The nominal money supply should set at 1,600.
Explanation:
Given that,
Money demand function: (M/P)d = 2,200 – 200r
r - Interest rate
Money supply (M) = 2,000
Price level (P) = 2
If the fed wants to set the interest rate at 7% then,
Money supply = money demand
= 
= 2,200 – 200r
P = 2 and r = 7%
= 2,200 – 200 × 7
M = 800 × 2
M = 1,600
The nominal money supply should set at 1,600.
Answer:
The statement is: False.
Explanation:
Many people have the wrong idea that writing long paragraphs is better to provide a more professional look to a study or report. However, in business especially, the optimal rule to follow is to be short and concise. Managers need information that will help them make decisions. Thus, the data provided must give clear conclusions from where the decisions can be taken. Wordy reports seem unuseful for that purpose.
Distillation is a process that can separate a mixture, composed of two or more components, by using selective evaporation and condensation. In this process is important to have the components with different boiling points, otherwise it's not possible to separate.
That means, that a good separation can be achieved if the boiling points have a large difference.
