A cognitive psychologist believes that people learn better when they spread out their studying over several days, so she creates

a study with three groups of participants. each group studies the same list of 120 chinese vocabulary words (none of the participants had studied chinese before. one group studies the words for 20 minutes on the first day. the second group studies the words for 20 minutes on the first and second days. the last group studies the words for 20 minutes on the first, second, and third days. on the fourth day, all of the participants are tested on how well they

A monopoly market is characterized by the inverse demand curve P = 1,200 – 40 Q and a constant marginal cost of $200. If the mar
Sergeeva-Olga [200]

Answer:

The profit maximizing output level declines by 2.5 units and the price rises by $100.

Explanation:

In a monopoly market the inverse demand curve is given as,

P = 1,200 - 40Q

The marginal cost of production of the last unit is $200.

The total revenue is

= Price\times Quantity

= 1,200Q - 40Q^{2}

The marginal revenue of the last unit is

= \frac{d}{dx} TR

= 1,200 - 80Q

At equilibrium the marginal revenue is equal to marginal price,

MR = MC

1,200 - 80Q = 200

80Q = 1,000

Q = 12.5

Putting the value of Q in the inverse demand function,

P = 1,200 - 40\times 12.5

P = $700

Now, if the marginal cost rises to $400,

At equilibrium the marginal revenue is equal to marginal price,

MR = MC

1,200 - 80Q = 400

80Q = 800

Q = 10

Putting the value of Q in the inverse demand function,

P = 1,200 - 40\times 10

P = $800

kow [346]

Answer:

Suppose that you purchased a conventional call option on growth in Non-Farm Payrolls (NFP) with an exercise price of 210,500 jobs. The NFP conventional contract pays out $85 for every job created in excess of the exercise price. a. What is the value of the option if job growth is 193,500.

The value of the option if job growth is 193,500 is $0.

Explanation:        

Since the job growth of 193,500 is less than the exercise price of 210,500 jobs, the value of the option on the contract in the given question is Zero.

Therefore, the value of the option if job growth is 193,500 is $0.

Custom Engines Company has the following estimated costs for the upcoming year: Direct labor costs $62,800 Direct materials used
jenyasd209 [6]

Answer:

Predetermined manufacturing overhead rate= $33.1 per direct labor hour

Explanation:

Giving the following information:

Salary of factory supervisor $37,800

Heating and lighting costs for factory $22,900

Depreciation on factory equipment $5500

The company estimates that 2000 direct labor hours will be worked in the upcoming year.

<u>To calculate the predetermined manufacturing overhead rate we need to use the following formula:</u>

Predetermined manufacturing overhead rate= total estimated overhead costs for the period/ total amount of allocation base

Predetermined manufacturing overhead rate= (37,800 + 22,900 + 5,500) / 2,000

Predetermined manufacturing overhead rate= $33.1 per direct labor hour

Faith Cassen has recently been hired as the manager of Gibraltar Coffee Shop. Gibraltar Coffee Shop is a national chain of franc
IrinaK [193]

Answer:

a.       I Disagree with Faith's method of handling this situation because she has not followed the internal control principle of safeguarding of assets. Stealing is a serious issue. An employee who can justify taking a box of tea bags can probably justify “borrowing” cash from the cash register.

b.      I Agree with Faith's method of handling this situation because Faith has followed the internal control principle of assignment of responsibility by making one employee responsible for the cash drawer and followed the internal control principle of segregation of duties (preparing the orders) from the accounting (taking orders and payments).

c.       I disagree with Faith's method of handling this situation because Faith has not followed the internal control principle of segregation of duties. It is true that faith has made one employee responsible however after cash counting another employee or Faith himself remove the cash register tape and compare the balance with cash drawer for effective internal control. Also, Faith’s standard of no mistakes may encourage the cashiers to overcharge a few customers in order to cover any possible shortages in the cash drawer.

Marlin Corporation reported pretax book income of $1,000,000. During the current year, the net reserve for warranties increased
jeyben [28]

Answer:

b. $233,100 tax expense

Explanation:

The computation of the current income tax expense or benefit is shown below:

But before that first we have to need to find out the taxable income i.e

= Pretak book income  + increase in net reserve warranties + exceeded amount - dividend deduction

= $1,000,000 + $25,000 + $100,000 - $15,000

= $1,110,000

Now to find out the current income tax expense since the tax rate is not given so we assume the marginal tax rate i.e 21%

So,

= $1,110,000 ×21%

= $233,100

By multiplying the taxable income with the tax rate we can get the income tax expense
