A company makes two products in a single plant. It runs this plant for 100 hours each week. Each unit of product A that the comp

any produces consumes two hours of plant capacity, earns the company a contribution of $1000, and causes, as undesirable side effects, the emission of 4 ounces of particulates. Each unit of product B that the company produces consumes one hour of capacity earns the company a contribution of $2000, and causes, as undesirable side effects, the emission of 3 ounces of particulates and 1 ounce of chemicals. The EPA (Environmental Protection Agency) requires the company to limit the particulate emission to at most 240 ounces per week and chemical emission to at most 60 ounces per week. Solve the problem in Excel and answer the following. The management wants to reduce the number of hours that the plant operates by 10 hours per week. By how much will the plant's profit drop if the management's decision is adopted

Answer:

Check the explanation

Explanation:

As per current limitation of emission, below will be the optimal solution.

The first attached image below is the screenshot of LP Table to be used to get the result -

The second attached image below is the formula used to get the result -

The third attached image below is the screenshot of solver with constraints, decision variable and objective -

the result is in the fourth attached image;

Product A - 15 units

Product B - 60 units

Total Contribution - 135000

Now EPA has allowed one additional unit of chemical emission. Hence, we will change the available quantity of chemical emission to 61 from 60. Rest all will be same as mentioned in earlier part. The fifth attached image below will be the updated optimal solution -

From the image, it is clear that company has 1 additional unit of particulate emission left (240-239), hence company can reduce the particulate emission by 1 units. Below will be the optimal solution -

Product A - 14

Product B - 61

Contribution - 136000 (increase in contribution by 1000)

Now, we can see that contribution has increased by 1000 which is equal to the contribution of 1 unit of product A.

1 unit of Product A is responsible for 4 unit of particulate emission. Hence company can reduce the emission further 4 units.

Final output will be as follows -

Product A - 13

Product B - 61

Contribution - 135000

Total Particulate Emission used = 13*4 + 61*3 = 235

Total Reduction in Particulate Emission = 240-235 = 5 units

Hence, company should willing to reduce the Particulate Emission by 5 units without affecting its Contribution Maximization objective.

Look in a recent issue of The Wall Street Journal at "NYSE-Composite Transactions."a. What is the latest price of IBM stock? b.
nydimaria [60]

Answer:

A) $191.08

B)  The annual dividend = $0.85 per share

     dividend yield = 1.78%

C) 3.14%

D) 13.74

E) $13.91

F) IBM's P/E  at 13.74 is higher than Exxon Mobil P/E at 11.29

G) The possible reasons for the difference in P/E is due to the difference in EPS earned by each company and also the difference in stock price of each company's stock

Explanation:

Referring the the recent issue of the wall street Journal at NYSE-Composite Transactions

A) The Latest price of IBM stock = $191.08

B)  What are the annual dividend payment and the dividend yield on IBM stock

The annual dividend = $0.85 per share

dividend yield = 1.78%

C) calculate what the yield will become if yearly dividend is moved up to $1.50

first we find the price per share

price per share = annual dividend per share / current dividend yield

                         = 0.85 / 1.78%  = 0.85 / 0.0178 = $47.75

since we now have the price per share value we can now calculate the dividend yield

dividend yield = annual dividend / price per share

                       = $1.50 / $47.75 =  0.0314

                       = 3.14 %

D) Calculate the P/E on IBM stock

 = 13.74 times as it was traded for the last 12 months

E) calculate IBM's earnings per share using P/E

 earnings per share = Price / P/E

 Latest  price of IBM stock = $191.08

  P/E = 13.74

 earnings per share =  191.08 / 13.74  = $13.91

F) IBM's P/E  at 13.74 is higher than Exxon Mobil P/E at 11.29

G) The possible reasons for the difference in P/E is due to the difference in EPS earned by each company and also the difference in stock price of each company's stock

irga5000 [103]

Answer:d

Explanation: Economic instability can include a volatile inflation rate and volatile rate of economic growth. It can involve higher unemployment and uncertainty about the economic cycle.

big fall in stock markets can trigger falls in consumer confidence and lead to a recession. The Wall Street crash of 1929 was a primary cause of the great depression. However, the stock market crash of 1987 did not cause an economic downturn. In fact, in the UK it was followed by an unprecedented economic boom. This was partly due to the way the government responded by cutting income tax and cutting interest rates. Interest rates are used as a tool in controlling inflation. However, they can also have an impact on consumer spending. Sometimes interest rates may have little impact; however, if they coincide with other factors they can cause a much bigger than expected fall in consumer spending. For example, in the UK, many homeowners have a variable mortgage. Therefore a small change in interest rates can have a big effect on disposable income. If an increase in interest rates was combined with another factor such as the slowing down of house price growth it may cause a big fall in spending. Number One priority to Target Economic growth and reduce unemployment. At the very least, economic growth needs to be close to long run trend rate 2.5%; it actually needs to be higher to catch up with lost spare capacity. Strong growth will help boost tax revenues and reduce unemployment. It is only in this climate you can successfully reduce the deficit. There is supply-side unemployment, especially in Europe, which has seen prolonged structural unemployment in past two decades. But, the fundamental cause is lack of aggregate demand
