Answer:
Equilibrium GDP = C+ I+ G+ X
Where: Y = GDP
C = Ca = a+bYd
I = Ig
G = G
X = Xn
Yd = Y-T
T = 0.2Y
Y = C+ I+ G+ X
Y = a + bYd + I +G + X
Y = a + b(Y-T) + I +G + X
Y = a + bY - bT + I +G + X
Y = a + by - b(0.2Y) + I +G + X
Y = a + bY - 0.2Yb + I +G + X
Y = a + 0.8Yb + I +G + X
Y - 0.8Yb = a + I +G + X
Y(1 - 0.8b) = a + I +G + X
Y = (a + I +G + X)/(1 - 0.8b)
That is the equilibrium GDP is Y = (a + I +G + X)/(1 - 0.8b)
Explanation:
Equilibrium GDP is also called equilibrium level of national income. This is the condition that must prevail for planned expenditure to exactly equals planned income or output in an economy. this is represented by the general equation of Y = C+ I+ G+ X-M but for the purpose of this question M which represent import was not introduced.
The consumption function of C = Ca = a+bYd is a Keynesian consumption function, it shows aggregate planned expenditure by household
Ig represents investment expenditure of the firm
Xn represents export while
G represents government expenditure on goods and services
T represents tax which varies with income level

Answer:
8.63%
Explanation:
The expected rate of return on the bond can be determined using a financial calculator bearing in mind that the calculator would be set to its end date before making the following inputs:
N=17(number of annual coupons in 17 years)
PMT=100(annual coupon=face value*coupon rate=$1000*10%=$100)
PV=-1120(the current price is $1,120)
FV=1000(the face value of the bon is $1000)
CPT
I/Y=8.63%
EXCEL APPROACH:
=rate(nper,pmt,-pv,fv)
nper=N=17
=rate(17,100,-1120,1000)
rate=8.63%
Based on the amount to be sold and the intended level of earnings, the selling price per unit should be<u> $3.40</u>
The Contribution margin needed is:
<em>= Fixed cost + Required earnings </em>
= 250,000 + 260,000
= $510,000
To get to this amount, the sales should be:
<em>Contribution margin = Sales x ( Selling price - Variable cost)</em>
510,000 = 250,000 × 0.6x
510,000 = 150,000x
x = 510,000 / 150,000
x = $3.40
In conclusion, the selling price is $3.40

Solution :
A firm hires labor till a point where the cost of hiring is equal to the value of the additional revenue it produces.
We know ,
the wage rate = cos of hiring an additional worker
the value of the additional revenue that the firm produces = price x (MPI) marginal product of the labor.
Therefore, the firm will hire when :
Wage = value of the additional revenue it generates
Thus, wage = price x (MPI) marginal product of the labor ...........(i)
Therefore, given :
wage of a worker = $ 45
Price = $ 12
So, 45 = 12 x MPI
MPI = 3.8
So the marginal product of employing three days of labor = 25-18/4-3 = 7
Marginal product of employing four days of labor = 30-25/4-3 = 5
So the 4th day produces less revenue than the cost that it generates.
So, the firm should hire 3 workers.
