a manufacturer makes two types of rubber, butadiene and polyisoprene. the plant has two machines, machine-1 and machine-2, which

are used to make the rubber strips. manufacturing one strip of butadiene requires 2.75 hours on machine-1 and 3 hours on machine-2. processing one strip of polyisoprene takes 3.5 hours on machine-1 and 4 hours on machine-2. machine-1 is available 180 hours per month, and machine-2 is available 200 hours per month. formulate an all-integer mathematical model that will determine how many units of each type of rubber should be produced to maximize profits if the profit contributions of butadiene and polyisoprene are $20 and $26, respectively.

The all-integer model that determines how many units of each type of rubber should be produced to maximize profits is given by:

  • Maximize: P(x,y) = 20x + 26y.
  • Constraint 1: 2.75x + 3.5y ≤ 180.
  • Constraint 2: 3x + 4y ≤ 200.
  • Constraint 3: x ≥ 0, y ≥ 0.

<h3>How to maximize profit?</h3>

The profit is maximized using linear programming, for a system of equalities/inequalities, in which the variables are given as follows:

  • Variable x: number of units of butadiene produced.
  • Variable y: number of units of polyisoprene produced.

The profit contributions of butadiene and polyisoprene are $20 and $26, hence the profit function is defined as follows:

P(x,y) = 20x + 26y.

The number of units is a countable amount, hence the values of x and y should be positive, and the constraint is of:

x ≥ 0, y ≥ 0.

Machine-1 is available 180 hours per month, hence the constraint relative to machine-1, considering the time needed for each unit, is of:

2.75x + 3.5y ≤ 180.

Machine-2 is available 200 hours per month, hence the constraint relative to machine-2, considering the time needed for each unit, is of:

3x + 4y ≤ 200.

Stocks A and B have the following data. Assuming the stock market is efficient and the stocks are in equilibrium, which of the f
IrinaK [193]

Answer: E) A's expected dividend is $0.75 and B's expected dividend is $1.20

Explanation:

Using the Gordon growth model, you can calculate the expected dividend. The formula is:

Price = Expected dividend/ (expected return - expected growth)

Stock A expected dividend

25 = D/ (10% - 7%)

D = 25 * 3%

= $0.75

Stock B expected divided

40 = D / (12% - 9%)

D = 40 * 3%

= $1.20

Option A, C and B are therefore wrong.

Option E is correct.

You are in the process of getting a new car but are not sure if you should buy or lease. The price of the car you want is $18,00
Mnenie [13.5K]

Answer:

You should buy the car.

Explanation:

Note: See the attached excel file for the worksheet that shows calculations of the present values of the Lease and Buy Options.

In the attached excel file, we have:

Net present value of Lease Option = $3,654.01

Total present value of Buy Option = $4,135.47

Difference = Total present value of Buy Option - Present value of Lease Option = $481.46

The Difference above shows that the total present value of Buy Option is greater than the net present value of Lease Option by $481.46.

Since the total present value of Buy Option of $4,135.47 is greater than the net present value of Lease Option of $3,654.01, you should buy the car.

WINSTONCH [101]

Karim and Rashida Sultan are filing a joint federal return. They have the following investment income $597 Frankfort Mutual Fund dividends, $283 Credit Union dividends. The amount of total taxable dividends reported on Schedule B is: $1,706.

Total taxable dividend=Craft Inc. dividends + Frankfort Mutual Fund dividends+ Credit Union dividends

Where:

Craft Inc. dividends=$826

Frankfort Mutual Fund dividends=$597

Credit Union dividends=$283

Let plug in the formula

Total taxable dividend= $826+$597+$283

Total taxable dividend=$1,706

Inconclusion if Karim and Rashida Sultan are filing a joint federal return. They have the following investment income $597 Frankfort Mutual Fund dividends, $283 Credit Union dividends. The amount of total taxable dividends reported on Schedule B is: $1,706.

Chamonix Chateau Rentals. You are planning a ski vacation to Mt. Blanc in Chamonix, France, one year from now. You are negotiati
nata0808 [166]

Answer:

The budgeted $ amount is  $13,680.88  

Explanation:

The purchasing power parity formula gives us an idea what an exchange spot rate would be in future period using the below formula:

Future spot rate=current spot rate*(1+US inflation)/(1+French inflation)

current spot rate=$1.3620

US inflation rate is 2.50%

French inflation is 3.50%

Future spot rate=$1.3620*(1+2.5%)/(1+3.5%)

future spot rate=$1.3488

The weekly cost of vacation would also be adjusted for inflation rate in France as follows:

Adjusted price=9800*(1+3.5%)=10143

Hence the cost of the one week rental would be 10143  multiplied by the future spot exchange rate of 1.3488 i.e $ 13,680.88   (10143*1.3488)

Both competitive firms and monopolies produce at the level where marginal cost equals marginal revenue. ​Then, other things rema
maria [59]

Answer:

A. Competitive markets face perfectly elastic demand and marginal​ revenue, while monopolies face​ downward-sloping demand and marginal revenue.

Explanation:

In the case when competitive firms and monopolies generated at the level in which the marginal cost is equivalent to marginal revenue keeping the other things constant so the price should be less in the competitive market as compared to the monopoly because in the competitive markets it face perfectly elastic demand but in the monopoly it face the down ward sloping demand curve

Therefore the option a is correct
