Answer:

(B) $0.50

Explanation:

The total cost is a function of the number of maps sold and the number of books sold. To determine the cost of each, a set of equations have to be solved simultaneously.

Let the cost of a map be m and that of a book be b

12m + 10b = 38

20m + 15b = 60

6m + 5b = 19

4m/3 + b = 4, b = 4 - 4m/3

6m + 20 - 20m/3 = 19

2m/3 = 1

m = 3/2 = 1.50

b = 4 - 4m/3

b = 4 - 2 = 2

The cost of a book is $2 while that of a map is $1.50

Hence a map sell for $0.50 less than a book.

When the elasticity of demand for a product is __________ the elasticity of supply, consumers pay __________ of the tax on the p
mezya [45]

When the elasticity of demand for a product is smaller than the elasticity of supply, consumers pay majority of the tax on the product.

The way the tax burden is distributed between purchasers and sellers is known as the tax incidence.

The relative price elasticity of supply and demand determines the tax incidence.

Usually, both the producers and the consumers of the taxed goods bear the incidence, or burden, of the tax.

But all we have to do is look at the elasticity of demand and supply to determine which group will be carrying the bulk of the load.

The majority of the tax burden falls on consumers when supply is more elastic than demand.

The majority of the tax burden falls on the producers when demand is more elastic than supply.

The less elastic the demand and supply are, the higher the tax revenue.

Hence, When the elasticity of demand for a product is smaller than the elasticity of supply, consumers pay majority of the tax on the product.

In a simple economy in which prices are constant and with no income taxes or imports, the marginal propensity to consume is 0.8.
lutik1710 [3]

Answer: Increase by $250

Explanation: As per the general rule of economics when there is an increase in income, that increase will eventually lead to increase in expenditure.

As, there is an increase in investment in the given case so it will result in increase in income for the economy.

We can compute it  as :-

change\:in\:income=\frac{change\:in\:investment}{1-MPC}

change\:in\:income=\frac{\$50}{1-0.8}

                                        = $250

Therefore, the expenditure would increase by $250

Sloan is a believer of the carrot-and-stick approach to behavior modification. As a leader, he reprimands his workforce and make
REY [17]

Sloan has adopted the “punishment” form of reinforcement towards his employees.

<u>Explanation:</u>

Punishment at the workplace means when new adopted changes or behavior lead to negative consequences at the workplace.

Sloan’s method of awarding only when the employees perform well is a case of the same. His action of deducting the employee's salary by 20 percent too would not positively encourage them to perform well, but lead to dissatisfaction and contempt towards him.

serg [7]

The question is incomplete as it does not contain values. The following is the complete question.

UPS, a delivery services company, has a beta of 1.2, and Wal-mart has a beta of 0.8. The risk-free rate of interest is 4% and the market risk premium is 7%. What is the expected return a portfolio with 40% of its money in UPS and the balance in Wal-Mart?

Answer:

The expected return of the portfolio is Portfolio r = 0.1072 or 10.72%

Explanation:

The expected return of a portfolio is the weighted average of the individual stocks' expected returns that form up the portfolio.

The formula for portfolio's expected return is as follows,

Portfolio r = wA * rA + wB * rB + ... + wN * rN

Where,

  • w is the weight of each stock in the portfolio
  • r is the expected return of each stock

To calculate the expected return of the portfolio, we will first calculate the expected return of UPS and Wal Mart using the CAPM equation.

The formula for expected return under CAPM is,

r = rRF + Beta * rpM

Where,

  • rRF is the risk free rate
  • rpM is the risk premium of market

r UPS = 0.04 + 1.2 * 0.07

r UPS = 0.124 or 12.4%

r Wal Mart = 0.04 + 0.8 * 0.07

r Wal Mart = 0.096 or 9.6%

Portfolio r = 0.4 * 0.124  +  0.6 * 0.096

Portfolio r = 0.1072 or 10.72%
