AVI supplies vended food to a large university. Because students kick the machines at every opportunity, management has a consta

nt repair problem. The machines break down on an average of three per hour, and the breakdowns are distributed in a Poisson manner. Downtime costs the company $25/hour per machine, and each maintenance worker gets $4/hour. One worker can service machines at an average rate of five per hour, distributed exponentially; two workers working together (as one team) can service seven per hour, distributed exponentially; and, a team of three workers can do eight per hour, distributed exponentially. What is the optimum maintenance crew size?

Answer:

The optimum maintenance crew size is 2 workers.

Explanation:

M/M/1 model for all: -

With one worker: λ= 3 per hour.

µ= 5 per hour.

Average number in system = λ/µ-λ =\frac{3}{5-3} = 1.5.

- With two workers: λ= 3 per hour µ= 7 per hour.

Average number in system = λ/µ-λ−=\frac{3}{7-3}=0.75.

- With three workers: λ= 3 per hour, µ= 8 per hour.

Average number in system = λ/µ-λ−=\frac{3}{8-3}=0.6.

# workers       λ      µ     (ns)    ($25*(ns))    ($4*(no.of workers)     Total cost

      1                3      5      1.5       37.50                         4                          $41.50

      2               3      7      0.75     18.75                         8                         $26.75

      3               3      8      0.6        15                             12                        $27.00

The optimum maintenance crew size is 2 workers.

You can purchase an item you need for a project for $10,000 and it has daily operating costs of $500, or you can lease the item
aleksandr82 [10.1K]

Answer:

On the 50th day, the purchase cost will be equal to the lease cost

Explanation:

Given that:

  • Daily operating costs of $500
  • Purchasing cost for the item:  $10,000
  • Lease amount: $700

Let x is the number of days the purchase cost be the same as the lease cost. As we now that:

The total cost should be equal to the total lease received

<=> 10,000 + 500x = 700x

<=> 200x = 10000

<=> x = 50

Hence, on the 50th day, the purchase cost will be equal to the lease cost

Which of the following should you do during an interview
stepladder [879]
Hey there!

The correct answer to your question is option A.

During an interview, you should tell stories of how worked with others to complete a project or solve problems.
This is because during an interview, you want whoever is interviewing you, to be comfortable with you and accept you! The other options won't make anyone want to accept you.

Hope this helps you.
Have a great day!

Sales                              $660,000            $340,000     $1,000,000

CM ratio                               63%                     78%                68.1%

Contribution margin     $415,800              $265,200       $681,000

Fixed expenses                                                               ($589,500)

Operating income                                                               $91,500

Revenue $1,000,000

<u>Period costs ($589,500)</u>

Operating income $91,500

Harlan enterprises manufactures smart phones. currently, harlan has $14,000 in raw materials and $25,000 in finished goods in it
Kitty [74]
Ideally;
Inventory = Cost of raw materials + Cost of finished goods + Cost of work-in-progress

Assuming this ideal case, Harlan's inventory would be;

Inventory = $14,000+$25,000+$18,600 = $57,600

However, if work-in-progress inventory was listed as $0;

Then, the  new work-in-progress would be;
Inventory = 57,600-18,600 = $39,000

This would reduce the inventory for Harlan Enterprises which may affect other financial ratios such as inventory turn-over ratio. As a result, such ratios will not reflect the exact position of the company.
