True. A monopolist does not face the same constraints as an open or free market but instead is bounded by the consumers' demand for its products. Therefore, the firm's decision about how much to supply is directly related to its demand curve because they can produce as much or as little as the consumes demand.
Answer:
r = 11.5%
Explanation:
Given data:
invested amount $20,000
withrawl amount after 5 year is $5000
Amount at the end of 10th yr is $50,000
present value is given as
![PV =\frac{ A}{(1 + r)^n}](https://tex.z-dn.net/?f=PV%20%3D%5Cfrac%7B%20A%7D%7B%281%20%2B%20r%29%5En%7D)
where
A - amount after given n year
![PV = \frac{5000}{(1 + r)^5} + \frac{50000}{(1 + r)^{10}}](https://tex.z-dn.net/?f=PV%20%3D%20%5Cfrac%7B5000%7D%7B%281%20%2B%20r%29%5E5%7D%20%2B%20%5Cfrac%7B50000%7D%7B%281%20%2B%20r%29%5E%7B10%7D%7D)
![20,000 = \frac{5000}{(1 + r)^5} + \frac{50000}{(1 + r)^{10}}](https://tex.z-dn.net/?f=20%2C000%20%3D%20%20%5Cfrac%7B5000%7D%7B%281%20%2B%20r%29%5E5%7D%20%2B%20%5Cfrac%7B50000%7D%7B%281%20%2B%20r%29%5E%7B10%7D%7D)
Let ![(1 + r)^5 = t](https://tex.z-dn.net/?f=%281%20%2B%20r%29%5E5%20%3D%20t%20)
squaring on both side
![(1 + r)^{10} = t^2](https://tex.z-dn.net/?f=%281%20%2B%20r%29%5E%7B10%7D%20%3D%20t%5E2)
![20,000 = \frac{5000}{t} + \frac{50000}{t^2}](https://tex.z-dn.net/?f=20%2C000%20%3D%20%20%5Cfrac%7B5000%7D%7Bt%7D%20%2B%20%5Cfrac%7B50000%7D%7Bt%5E2%7D)
![20 = \frac{5}{t} + \frac{50}{t^2}](https://tex.z-dn.net/?f=20%20%3D%20%5Cfrac%7B5%7D%7Bt%7D%20%2B%20%5Cfrac%7B50%7D%7Bt%5E2%7D)
![20 t^2 - 5t - 50 = 0](https://tex.z-dn.net/?f=20%20t%5E2%20-%205t%20-%2050%20%3D%200%20)
solving for t we get
t = 1.711
so, ![r = 1.711^{1/5} -1 = 0.115 = 11.5\%](https://tex.z-dn.net/?f=r%20%3D%201.711%5E%7B1%2F5%7D%20-1%20%3D%200.115%20%3D%2011.5%5C%25)
The marginal cost of the second meal deal is $5.
<h3>What is the marginal cost?</h3>
The marginal cost is the change in total cost when consumption is increased by one unit.
Marginal cost = change in total cost / change in consumption
($15 - $10) / (2 - 1) = $5

Answer:
Remains constant
Explanation:
Since the same set of resources are useful in producing both cars and trucks, it shows that resources are not specialized hence Russia has a straight line PPC. A straight line (linear) PPC connotes constant returns to scale. In this case, resources are mobile and can easily be reallocated and redirected from the production of one good to another thus, opportunity cost is constant and so is the marginal rate of transformation (MRT). The MRT is the number of units or amount of a good that must be foregone in order to attain one unit of another. If Russia decides to produce more cars and fewer trucks, the resources deployed in producing more cars would be well suited as the resources already used in car production. The opportunity cost in producing each additional unit of car remains constant as more cars are produced.
The slope of a linear PPC determines the marginal rate of transformation; that is, a flatter slope would mean producing more cars requires trading-off fewer trucks while a steeper slope would mean that producing more cars requires trading-off more trucks.
