Answer:
The country has closed economy; it means there is no other trading relation with, outside countries. Export imports do not affect the economy of the country, and here is no government interference as mentioned in the question. This is a self sufficient country, its demand fulfilled from inside of the country. So its aggregate price levels and interest rate are fixed. MPC or the marginal propensity to consume indicates whether there is an increase in disposable income or increase in consumption. Here consumption increases equal to the increase in the income.
MPC = ΔC /ΔY which is constant here.
The increase in income in this country is mostly permanent and increases in a fix period of time and proportionately.
C= 200 +0.75 YD (YD is disposable income), Y=75, GDP =$900
The economy achieves it’s equilibrium level when supplies meets demand or the GDP is equals to it’s total expenditure. MPC is a fraction between 0 and 1 , MPC means a change in consumption brings the change in YD . here the MPC is equals to MPS which means the change in saving bring by the change in disposable income. All income here saved or consumed. So the change in income equals to the change in consumption or saving.
MPC+ MPS = 1
So the average propensity to consume is proportionate to income which is spend on consumption. APC= C/ YD. And the average proportionate to save is equals to income saved APS= S/YD . so here APC +APS = 1. The increase in production or price leads to the increase in the total value of output, that is the equilibrium condition.
Explanation:
Answer:
Acitivy B should be crashed first by 2 days and Activity B has a crash cost per days of $25, it will be crashed for a total of $50.
Explanation:
activity A =
normal time (NT) = 5 days
Normal cost (NC) = $0
crash time (CT) = 3 days
Crash cost (CC) = $500
crash cost per day = [CC - NC]/[CT - NT] = $250/day
activity B:
normal time (NT) = 6 days
Normal cost (NC) = $0
crash time (CT) = 4 days
Crash cost (CC) = $50
crash cost per day = [CC - NC]/[CT - NT] = $25/day
activity C:
normal time (NT) = 8 days
Normal cost (NC) = $0
crash time (CT) = 3 days
Crash cost (CC) = $1000
crash cost per day = [CC - NC]/[ CT- NT] = $200/day
The activity that takes the least cost to speed up is the first one to be crashed. from the computations, activity B takes the least cost to speed up, so the project manager should crash activity B first by 2 days.
Therefore, Acitivy B should be crashed first by 2 days and Activity B has a crash cost per days of $25, it will be crashed for a total of $50.
Answer:
The probability that neither of both stocks increase is 0,14
Explanation:
The Complement Rule states that the sum of the probabilities of an event and its complement must equal 1.
The data we have is the probability that Stock A or B increase, we are looking for the probability that neither occur, so we have to use the complement of each one.
Complement of Stock A =1-0.54=0.46
Complement of Stock B =1-0.68=0.32
If we want to know the probability of both events happening we have to multiply both complements.
Probability that neither of these two events will occur= 0.46 x0.32= 0,1472
Answer:
E. efficiency wages
Explanation:
Clearly this isn't a discrimination case, as Rob has a robust background with the company (15 years). Although their work output may be the same, Rob's experience justifies the higher pay.
This is one form of efficiency wage theory, holding that higher wages lead to increased employee productivity. This way, Rob gets an incentive for staying with the company.
Answer:
PV of lease annuity is $25000
Explanation:
As the paymengt will be made at the end of the year, the annuity is an ordinary annuity. We will calculate the present value of the ordinary annuity using the following formula,
PV Annuity = PMT * [( 1 - (1+r)^-n) / r]
Where,
- PMT is periodic payment
- r is discount rate per peiod
- n is number of periods
Thus,
PV of annuity = 3895.5 * [( 1 - (1+0.09)^-10) / 0.09]
PV of annuity = $24999.985 rounded off to $25000
