Answer:
also known as a financial return, in its simplest terms, is the money made or lost on an investment over some period of time. A return can be expressed nominally as the change in dollar value of an investment over time.
Explanation:
It will decrease
because the marginal productivities of workers will decrease. Diminishing marginal product occurs when the
marginal product of an input goes down as the quantity of the input goes up. The transformation in product resulting from
employing one more unit of a particular input for instance, the change in
output when a firm's labor is mark up from five to six units, assuming that the
mass of other product are kept constant is
called The input of marginal product or marginal physical product.
Answer:
Option D.
Explanation:
Given information:
![Q_1=200, Q_2=400](https://tex.z-dn.net/?f=Q_1%3D200%2C%20Q_2%3D400)
![P_1=225, P_2=175](https://tex.z-dn.net/?f=P_1%3D225%2C%20P_2%3D175)
Formula for price elasticity of demand is
![E_d=\frac{Q_2-Q_1}{P_2-P_1}\times \frac{P_1+P_2}{Q_1+Q_2}](https://tex.z-dn.net/?f=E_d%3D%5Cfrac%7BQ_2-Q_1%7D%7BP_2-P_1%7D%5Ctimes%20%5Cfrac%7BP_1%2BP_2%7D%7BQ_1%2BQ_2%7D)
Substitute the given values in the above formula.
![E_d=\frac{400-200}{175-225}\times \frac{225+175}{200+400}](https://tex.z-dn.net/?f=E_d%3D%5Cfrac%7B400-200%7D%7B175-225%7D%5Ctimes%20%5Cfrac%7B225%2B175%7D%7B200%2B400%7D)
![E_d=\frac{200}{-50}\times \frac{400}{600}](https://tex.z-dn.net/?f=E_d%3D%5Cfrac%7B200%7D%7B-50%7D%5Ctimes%20%5Cfrac%7B400%7D%7B600%7D)
![E_d=-\frac{8}{3}](https://tex.z-dn.net/?f=E_d%3D-%5Cfrac%7B8%7D%7B3%7D)
![E_d\approx -2.67](https://tex.z-dn.net/?f=E_d%5Capprox%20-2.67)
Absolute value is
![|E_d|= |-2.67|=2.67](https://tex.z-dn.net/?f=%7CE_d%7C%3D%20%7C-2.67%7C%3D2.67)
The absolute value of the price elasticity of demand for DVD players is 2.67.
Therefore, the correct option is D.
I don’t know the answer I just need the points like really badly and I’m really sorry
