Carlos is a hard-working college senior. One Saturday, he decides to work nonstop until he has answered 100 practice problems fo

r his physics course. He starts work at 8:00 AM and uses a table to keep track of his progress throughout the day. He notices that as he gets tired, it takes him longer to solve each problem.
Time Total Problems Answered
8:00 AM 0
9:00 AM 40
10:00 AM 70
11:00 AM 90
Noon 100
Use the table to answer the following questions.

The marginal, or additional, gain from Carlos’s second hour of work, from 9:00 AM to 10:00 AM, isproblems.

The marginal gain from Carlos’s fourth hour of work, from 11:00 AM to noon, isproblems.

Later, the teaching assistant in Carlos’s physics course gives him some advice. "Based on past experience," the teaching assistant says, "working on 25 problems raises a student’s exam score by about the same amount as reading the textbook for 1 hour." For simplicity, assume students always cover the same number of pages during each hour they spend reading.

Given this information, in order to use his 4 hours of study time to get the best exam score possible, how many hours should he have spent working on problems, and how many should he have spent reading?

a. 1 hour working on problems, 3 hours reading
b. 2 hours working on problems, 2 hours reading
c. 3 hours working on problems, 1 hour reading
d. 4 hours working on problems, 0 hours reading

Assume that the labor market for barbers is competitive and that it is differentiated into two groups:
ehidna [41]

Answer and Explanation:

I will go through each and every option explaining the reasons and what option would be the best:

The (a) part says 'difference in wages will eventually disappear since a haircut is a homogeneous good' - This is not true because even though it is an homogeneous product, some customers do have a strong preference for barbers who are not going bald. Therefore, they know their worth and they would want to capitalize on that and get paid just a bit more than bald barbers.

The (b) part says 'barbershops that hire barbers with hair will be able to charge a higher price for a haircut to those consumers who have a strong preference for barbers with hair'. - If the barbershop charges higher price for barbers that have hair then the customers will prefer bald barbers as the questions mentions that there is high competition and since it is an homogeneous, customers would be willing to save money and get their haircut from some other barber.

The (c) part says 'barbershops that hire bald barbers will always be much more profitable' - Not necessarily. The reason is that some customers have a strong preference for barbers who are not bald and therefore, that would help barbershops who have barbers with hair to be a bit more profitable as some additional customers would want their services.

The (d) part says 'barbershops that hire barbers with hair will always be much more profitable' - This is the best option and the reason for it is because some customers have a strong preference for barbers with hair and that would help the barbershop to earn more. They would have the customers who already indifferent to whoever cuts their hair and in addition to that, they would also have the customers who have their preference.

Hence the answer is D.

On January 8, Lowrence Co. issued a $60,000, 120-day discounted note to Raines Bank. The discount rate is 8%. Assuming a 360-day
Salsk061 [2.6K]

Answer:

a. $58,400

Explanation:

A discounted note, will make the person receive a lesser amount than the amount due at maturity. This way the person who grants the note is receiving interest for borrowing.

<em><u>Calculations</u></em>

principal x discount rate x time = discount

<em><u>Where</u></em> rate and time should be expressed in the same metric IE if the rate is annual express time in portion of years if it is monthly, in months.

60,000 x 0.08 x 120/360 = 1,600

Now, we subtract this amount form the nominal:

nominal - discount = net

60,000 - 1,600 = <u>58,400</u>
