Tammi’s Truck Stop sells Seat-o-Nails cushions, which are specially designed to keep drivers awake on the road. Her accessories

supplier makes deliveries every Tuesday, at which times she can get as many cushions as she wants (the supplier’s truck carries a large number of cushions). The cushions cost $40 wholesale, and Tammi sells them for $65. She also uses a 35 percent interest rate to evaluate the cost of holding inventory. Today it is Tuesday, Tammi has 12 cushions in stock, and the supplier has just arrived. Assuming that the weekly demand is normally distributed with mean 35 and standard deviation 10, answer the questions below. (hint: use newsvendor model)How many cushions should Tammi buy if sales are lost when she runs out of stock during the week?Reconsider part (a) if unmet demand is not lost but it is back ordered, and it costs Tammi $12 to mail the cushion to the customer.

Answer:

Explanation:

(a) The cost of underage(Cu) will be the opportunity cost for lost sales which will be:

= 65 - 40

= 25

The cost of overage(Co) will be the holding cost which will be:

= 40 x 35%/52

= 40 × 0.35/52

= 40 × 0.0067308

= 0.269

The Critical ratio will be:

= Cu/(Cu + Co)

= 25/(0.269+25)

= 0.9894

For the optimal condition,

F(z) = Critical ratio = 0.9894,

therefore, z = normsinv (0.9894) = 2.30

Therefore, the optimal stock will be calculated as:

= Mean demand + (z × Stdev)

= 35 + (2.30 × 10)

= 35 + 23

= 58 units.

We should note that Tammi already has 12 cushions in stock, therefore the order quantity will be:

= 58 - 12

= 46 units

(b) Cu = 12

Co = 0.269

Critical ratio will be:

= Cu/(Co + Cu)

= 12 / (12 + 0.269)

= 0.9781

Therefore, z = normsinv(0.9781) = 2.0

Then, the optimal stock will be:

= 35 + (2.0 × 10)

= 35+20

= 55 units

We should note that Tammi already has 12 cushions in stock, therefore the order quantity will be:

= 55 - 12

= 43 units

Economic models
Fiesta28 [93]

Answer:

D.

Explanation:

A economic model can be used to explain or predict economic phenomena, because every model has to have key variables that command the economic decisions and operations.

An economic model is define to get a specific goal, so when some problem comes, you can study every decision based on the model applied, that 'simplifies' solutions, or even better, you must be able to predict when economic problems will arrive.

Suppose changes in autonomous consumption affect investment while changes in autonomous government spending do not. in this case
Charra [1.4K]
 in this case, identical changes in autonomous consumption and autonomous government spending: <span> have different effects on equilibrium income

When a factor is implemented and have two different reaction, it is safe to assume that that factor have two different effects.
For example, an increasing interest in technology(autonomous consumption) may increased the investment for tech products. The government spending may not give as much influence in this context because it wont affect the transaction between the customers and the producer

Which one of the following basic patterns of demand is difficult to predict because it is affected by national or international
alexdok [17]

Answer: D) cyclical

Explanation:

Cyclical Demand is difficult to predict because it goes according to the business cycle and hence is affected on a Macro Economic scale by events at a National or International level.

This means that something could be in demand today but the demand could fall or rise sharply based on the stage of the business cycle the economy is in.

Because manufacturers with jit systems produce merchandise closer to the time of sale, they can
wlad13 [49]
<span>These companies are able to reduce the inventories required to satisfy the demand of the retailers. With a JIT system, the company does not have to worry as much about waste product or overproducing, since the final item is being manufactured just before the deadline. This allows the company to run on a much tighter production schedule and lessens waste.</span>

The following information is available for the month of April from the First department of the Armque Corporation: Units Work in
miskamm [114]

Answer:

Direct Materials = 340,000

Direct Labor       = 304,000

Explanation:

The concept of equivalent units measures the number of units to the extend of completion  of inputs added to outputs during the production.

The first step is to determine the units completed and transferred.

units completed and transferred = opening work in process + started during the year - closing work in process

                                                      = 90,000 + 250,000 - 60,000

                                                      = 280,000

then determine the equivalent units of production with respect to direct materials and conversion costs.

<u>Direct Materials</u>

Note : Materials are added in the beginning of the process thus 100 % in all categories.

units completed and transferred (280,000 × 100%) = 280,000

units of closing work in process (60,000 × 100%)    =   60,000

Total                                                                             =  340,000

<u>Conversion Cost</u>

units completed and transferred (280,000 × 100%) = 280,000

units of closing work in process (60,000 × 40%)    =     24,000

Total                                                                             =  304,000
