Answer:

C) the horizontal sum of all the individual firms' supply curves.

Explanation:

The main characteristics of a perfectly competitive market is that the number of suppliers and consumers is very large, and the products or services supplied are all identical or extremely similar. That means that all the products or services supplied are substitutes from each other. E.g. a bushel of wheat is the same whether is was grown in Kansas or Ohio. This results in all suppliers and consumers being price takers, since no one has enough market power to determine the price.

The supply curve in a perfectly competitive market is upward sloping, meaning that at a higher price, suppliers will be willing to sell more products or services. To determine the total market supply curve, you must add together all the individual supply curves from every supplier. The same should be done with the market demand curve, only that you need to add together all the individual supply curves from every consumer. Since the supply curves are upward sloping, you must add horizontally.

Answer: C.) Horizontal sum of all the individual firm's supply curve

Explanation: A perfectly competitive market, is that in which sellers or suppliers of a certain product are numerous such that a slight increase in price, and demand could fall to 0. Here, an individual seller has no control over the price of commodities. The supply curve tells how much quantity will be produced at different prices. Therefore the market supply curve is determined by all individual sellers individual price in other to determine the overall quantity to be produced at varying market price. Prices are drawn horizontally from the y-axis to determine quantity produced at different prices for each indivudual seller which is summed to generate the market supply curve.

Assume your goal in life is to retire with $2,500,000. How much would you need to save at the end of each year if interest rates
LUCKY_DIMON [66]

Answer:

Annual deposit= $60,982.31

Explanation:

Giving the following information:

Future Value= $2,500,000

Number  of periods= 20 years

Interest rate= 0.07

<u>To calculate the annual deposit, we need to use the following formula:</u>

FV= {A*[(1+i)^n-1]}/i

A= annual deposit

Isolating A:

A= (FV*i)/{[(1+i)^n]-1}

A= (2,500,000*0.07) / [(1.07^20) - 1]

A= 60,982.31

andre [41]

Answer:

Direct labor rate variance= $594 unfavorable

Explanation:

Giving the following information:

The standard direct labor cost per hour is $7.20.

During August, Zanny's water ski radio production used 6,600 direct labor-hours at a total direct labor cost of $48,708.

<u>To calculate the direct labor rate variance, we need to use the following formula:</u>

Direct labor rate variance= (Standard Rate - Actual Rate)*Actual Quantity

Actual rate= 48,078/6,600= $7.29

Direct labor rate variance= (7.20 - 7.29)*6,600

Direct labor rate variance= $594 unfavorable

1. You have a portfolio that is invested 21% in Stock A, 34% in Stock B, and 45% in Stock C. The betas of the stocks are .66, 1.
MrMuchimi

Answer:

1.

Portfolio Beta = 1.225 rounded off to 1.23

Option e is the correct answer.

2.

r = 0.13338 or 13.338% rounded off to 13.34%

Explanation:

1.

The portfolio beta is a function of the weighted average of the individual stocks' betas that form up the portfolio. To calculate the beta of a portfolio, we use the following formula,

Portfolio Beta = wA * Beta of A  +  wB * Beta of B  + ... + wN * Beta of N

Where,

w is the weight of each stock

Portfolio Beta = 0.21 * 0.66  +  0.34 * 1.21  +  0.45 * 1.5

Portfolio Beta = 1.225 rounded off to 1.23

2.

Using the CAPM, we can calculate the required rate of return on a stock. This is the minimum return required by the investors to invest in a stock based on its systematic risk, the market's risk premium and the risk free rate.

The formula for required rate of return under CAPM is,

r = rRF + Beta * (rM - rRF)

Where,

rRF is the risk free rate

rM is the market return

r = 0.037  +  1.22 * (0.116 - 0.037)

r = 0.13338 or 13.338% rounded off to 13.34%
