<span>Price transparency. This best describes the amount of truth or transparency about something. Complete information doesn't necessary represent somebody's understanding of something, but rather describes if all parts of said information were present to seen, heard, felt..etc.</span>
A. The Occupational Outlook Handbook
I think the most appropriate answer would be "a car dealership salesman" would be the opportunity cost.
I hope it helped you!
Answer:
X (the variable on the horizontal axis) will increases by 2.
Explanation:
The slope of a straight line is -3. So, m=6.
Slope of a straight line is

Y (the variable on the vertical axis) decreases by 6.
Change is y = -6
We need to find the change in (the variable on the horizontal axis).
Substitute the given values in the above formula.



Note: All options are incorrect.
Therefore, X (the variable on the horizontal axis) will increases by 2.
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.
