Explanation:
The teachers that Sam imitates constitute <u> models </u> for him.
One of the first learning modes that every human use is the imitation. A baby can learn by direct experience (if he touches a metallic surface in winter the baby learns it is cold) or by imitation: when the baby sees the mom talking the baby learns to move the lips. The mother is baby's first model and the baby learns by imitating her.
When we grow up, we have many models: relatives, friends, peers, teachers, and virutally any person with whom we are in contact.
Imitating continues during all the life and teachers are very important models.
Specially, when the teacher is a good example and arouses admiration, the students will trend to imitate them. Particularly, in the case of Sam who wants to be a teacher: probably Sam has had some excellent teachers whom he admires and made him to want to follow their steps, which is why he imitates them. They are a good model to follow.
Answer:
D. $162
Explanation:
We know,
Using high-low method, variable cost per unit = (Highest maintenance expense - Lowest maintenance expense) / (Highest machine hours - Lowest machine hours)
Given,
Highest maintenance expense = $4,360
Lowest maintenance expense = $2,950
Highest machine hours = 2,500 hours
Lowest machine hours = 1,660 hours
Therefore,
Variable cost per unit = $(4360 - 2950)/(2500 - 1660)
Variable cost per unit = 1410/840 = 1.68
Total Fixed cost using lowest machine hours =
Total cost - (variable cost per unit x least machine hours)
= 2,950 - (1.68*1,660)
= $162
Answer: The stock price is expected to be $57 a share one year from now.
Explanation:
The stock price is expected to be $57 a share one year from now.
Expected return = 14%
current share price= $50
expected share price in a year from now = $50 x (1 + 0.14)
expected share price in a year from now = 57
Answer: 20 units.
Explanation:
Given that,
Inverse demand curve: P = 420 - 2Q
There are five firms and each of the firm has a constant marginal cost.
Marginal cost (MC) = 20
Profit maximizing output is produced by the firms is at a point where the marginal cost is equal to marginal revenue.
P = 420 - 2Q
Total revenue(TR) = PQ
= 420Q - 2
Differentiating TR with respect to 'Q'
Marginal revenue(MR) = 420 - 4Q
MR = MC
420 - 4Q = 20
Q = 
Q = 100
Therefore, output produced by the industry is 100 units.
Per-firm production = 
= 
= 20 units
Hence, each firm produces 20 units.
