Answer: (b) -3.08
Explanation:
The relationship between the demand(q), price per unit product(p) and the disposable income,yd is given by the expression below;
q= 20ln(7yd-2p).
From the expression above, the marginal demand,
∂ q/∂ p is the differential of the equation of relationship between the demand, price and disposable income.
This involves considering the demand,q as the dependent variable and the price per unit product,p as the independent variable and the disposable income,yd is considered constant.
Therefore ,
∂ q/∂ p= (-40)÷(7yd-2p)
By substitution of
yd =$3000÷1000= $3
and p= $4
∂ q/∂ p= (-40)÷((7×$3)-(2×$4))
∂ q/∂ p= -40÷13= 3.08
Please see the attachment for knowledge on how ∂ q/∂ p was obtained.
Answer:
$1.07
Explanation:
The marginal cost measures the change in total cost of adding on more worker divided by the change in product for this additional worker (marginal product of labor). When adding one more worker, costs will increase by $80 (wage rate), while product will increase by 75. Therefore, the marginal cost is:
The marginal cost is $1.07.

Answer:
labor force growth and productivity growth.
Explanation:
A country's long run growth rate is generally calculated by adding the increases in the market value of the goods and services produced within a country during a period of time. It is generally stated as a percentage growth of real GDP.
The real GDP's growth rate is determined by two factors: labor force growth and productivity growth. So it is determined by the growth in productivity, demographic growth and labor force participation.
