A small company that shovels sidewalks and driveways has 100 homes signed up for its services this winter. It can use various co

mbinations of capital and labor: lots of labor with hand shovels, less labor with snow blowers, and still less labor with a pickup truck that has a snowplow on front. To summarize, the method choices are:
• Method 1: 50 units of labor, 10 units of capital
• Method 2: 20 units of labor, 40 units of capital
• Method 3: 10 units of labor, 70 units of capital

If hiring labor for the winter costs $100/unit and a unit of capital costs $400, what production method should be chosen? What method should be chosen if the cost of labor rises to $200/unit?

Answer:

(i) Method 1

(ii) Method 1

Explanation:

(i) Let L denote units of labor and C denote units of capital. Initially, the cost function for each method is given by the following expression:

M_i = \$100*L_i+\$400*C_i

Applying the given values for all three methods, the one with the lowest cost should be picked:

M_1= \$100*50+\$400*10\\M_1 = \$9,000\\M_2= \$100*20+\$400*40\\M_2 = \$18,000\\M_3= \$100*10+\$400*70\\M_3 = \$29,000

Therefore, Method 1 should be picked.

(ii) If the cost of labor rises to $200/ unit:

M_1= \$200*50+\$400*10\\M_1 = \$14,000\\M_2= \$200*20+\$400*40\\M_2 = \$20,000\\M_3= \$200*10+\$400*70\\M_3 = \$30,000

Method 1 is still the most cost attractive method.

Answer:

Method 1 should be chose, since it is still the cheapest if labor cost rises to $200/unit.

Explanation:

Total Cost = ( units * labor costs) + (capital cost * units of labor)

Total Cost for Method 1 : (50 * 100) + (10*400)

= $9,000

Total Cost for Method 2 : (20 * 100) + (40*400)

= $18,000

Total Cost for Method 3 : (10 * 100) + (70*400)

= $29,000

If  the price of labor rises to $200 then:

Total Cost for Method 1 : (50 * 200) + (10*400)

= $14,000

Total Cost for Method 2 : (20 * 200) + (40*400)

= $20,000

Total Cost for Method 3 : (10 * 200) + (70*400)

= $30,000

Suppose a family has saved enough for a 10 day vacation (the only one they will be able to take for 10 years) and has a utility
Harlamova29_29 [7]

Answer:

2 Days

Explanation:

First, there is the need to rewrite the utility function for clarity

U=V^{1/2}

1. The Probability of Falling ill by someone in the family is given as 20%

2. If someone should fall ill, the total number of days that would be spoiled is calculated as:

Total number of vacation= 10 days x Probability to fall ill = 20%

= 10 x 0.2 = 2 days

This means if someone should fall ill based on the probability, then 2 out of the total 10 days can be ruined

3. The number of days for vacation days to enjoy is 10-2 = 8 days

This means if the family gives up 2 days of probable illness, they can still enjoy their vacation.

V= 2 days

When a non-price factor changes--such as technology, expectations, prices of related goods, prices of inputs, or the number of s
ludmilkaskok [199]

Answer:

The answers are:

  1. D) Supply and the entire curve shifts.
  2. D) Quantity supplied and the supply curve does not shift.

Explanation:

1. When non price factors (that affect the supply of a product) change, then the whole supply curve shifts and the quantity supplied will vary.

For example, new machinery that produces goods in a more efficient way, will shift the entire supply curve to the right. Suppliers will be able to produce more goods at the same costs.

2. A change in the amount of goods produced due to a change in price, is a change in the quantity supplied of that product. Suppliers will produce more goods at higher prices. But those changes in the quantity supplied happen follow the supply curve.

viktelen [127]

Answer:

INCREASE IN AVERAGE INVENTORY VALUE REQUIRED = $2.25 million

Explanation:

Inventory turnover will be determined as :

Inventory turnover = Annual sales ( at cost ) / Inventory value

Annual sales this year = $72million

Inventory turnover = 8 times

Therefore , Inventory value of current year = $72/8 =$ 9 MILLION

If annual sales ( at cost ) increases by 25%, Inventory value also has to increase by 25% to maintain the same inventory turnover ratio next year

Therefore , increase in average inventory value required = 25% of $9 million = $2.25 million

INCREASE IN AVERAGE INVENTORY VALUE REQUIRED = $2.25 million

The Investments Fund sells Class A shares with a front-end load of 5% and Class B shares with 12b-1 fees of 0.75% annually as we
elena-14-01-66 [18.8K]

Answer:

The responses to the given choices can be defined as follows:

Explanation:

Assume is the investment. Each original Class A investment is of the net-front unburden. The portfolio will be worth four years from now:  

\$1,000 \times 5\% = \$50 =\$1,000 - \$50 = \$950\\\\         \$950 (1 + 0.13)^4 = \$950 (1.13)^4 = \$950 (1.630474) = \$1,548.95\\\\  

You will place the total of \$1,000 on class B shares, but only 12b-1will be paid (13-0.75 = 12.25) at a rate of 12.25\% and you'll pay a 1\%back-end load charge if you sell for a four-year period.

After 4 years, your portfolio worth would be:      

\$1,000 (1 + 0.1225)^4 = \$1,437.66   \\\\      \$1,000 (1.1225)^4 = \$1000 (1.587616) = \$ 1,587.62  

Their portfolio worth would be: after charging the backend load fee:      

\$1,587.616 \times 0.99 = \$1,571.74   \\\\                     Amounts     \\\\     Class A \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \     1,548.95\\\\          Class B \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \     1,571.74 \\\\

When the horizon is four years, class B shares are also the best option.

Class A shares would value from a 12-year time frame:

\$950 (1.13)^{12} = \$950 (4.334523) = \$4,117.80  \\\\

In this case, no back-end load is required for Class B securities as the horizon is larger than 5 years.

Its value of the class B shares, therefore, is as follows:

\$1,000 (1.1225) 12 = \$1,000 (4.001623) = \$4,001.62 \\\\Amounts    \\\\\      Class A \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ 4,117.80\\\\          Class B \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \   4,001.62\\\\

Class B shares aren't any longer a valid option in this, prolonged duration. Its impact on class B fees of 0.75\%\ \ 12b-1cumulates over a period and eventually outweighs the 5\% the burden of class A shareholders.
