The daily demand for parts from a machining workcell JMB to an assembly workcell is 1,600 units. The average processing time is

Karolina [17]

Answer:

Daily demand for parts = 1600 units

Avg processing time = 25 seconds.

Capacity of a container = 250 units

Waiting time of a container before the JMB = 6 hours

Number of containters currently deployed = 10

Solution:

Total number of parts carried by the containter = 10 x 250 = 2500 parts.

Total numbers carried in excess as safety stock = 2500-1600 = 900

Percentage of safety stock = (900/1600) x 100 = 56.25%

If one container is removed total parts carried = 2250 units

Processing time at machine for 250 parts after loading in JMB = 250 x 25 seconds = 1.736 hours, but it has to wait for another 4.26 hours for the next container to be loaded because of the waiting time of the containter is 6 hours.

Processing time at machine for 1600 parts = 1600 x 25 seconds = 11.11 hours

Number of containers required for 1600 parts = 1600/250= 6.4 ~ 7 containters

Waiting time of 7 containers = 7 x 4.26 = 29.82 hours.

If one of the containers has to be removed 1600 parts has to be carried in 6 containers ie., 29.82hours - 6 hours = 23.82hours

Waiting time per container before loading = 23.82/6 = 3.97 hours.

Reduced Total waiting time of the container = 3.97 hours + the processing time of 250 parts = 3.97 + 1.736 =5.7hours ~ 5 hours and 42 minutes

A particular plot of land can produce 700 kg of beef per hectare. beef sells for $4/kg. if that land is converted to producing c

Brums [2.3K]

The computation shows that the amount that will be made will be $420.

<h3>How to compute the value?</h3>

From the information, it was stated that a particular plot of land can produce 700 kg of beef per hectare. beef sells for $4/kg.

It was then stated that if that land is converted to producing corn, which sells for $0.15/kg, approximately how much will the farmer make selling corn.

The amount made will be:

= 700 × 4 × 0.15

= 700 × 0.6

= $420

Arbor Systems and Gencore stocks both have a volatility of 33%. Compute the volatility of a portfolio with 50% invested in each

fiasKO [112]

Answer:

<h3>In case of b, c, d ,e volatility is less than that of original stock</h3>

Explanation:

The formula to compute the volatility of a portfolio

$=\sqrt{W_1^2\sigma_1^2+W_2^2\sigma_2^2+2W_1W_2\sigma_1\sigma_2*c}$

Here,

The standard deviation of the first stock is σ₁

The standard deviation of the second stock is σ₂

The weight of the first stock W₁

The weight of the second stock W₂

The correlation between the stock c

a) If the correlation between the stock is +1

$=\sqrt{W_1^2\sigma_1^2+W_2^2\sigma_2^2+2W_1W_2\sigma_1\sigma_2*c}$

$=\sqrt{(0.5\times0.33)^2+(0.5\times0.33)^2+(2\times(0.5\times 0.33)\times(0.5\times0.33)\times1} \\\\=0.33$

Hence, the volatility of the portfolio is 0.33 0r 33%

b) If the correlation between the stock is 0.50

$=\sqrt{W_1^2\sigma_1^2+W_2^2\sigma_2^2+2W_1W_2\sigma_1\sigma_2*c}$

$=\sqrt{(0.5\times0.33)^2+(0.5\times0.33)^2+(2\times(0.5\times 0.33)\times(0.5\times0.33)\times0.5} \\\\=0.29$

Hence, the volatility of the portfolio is 0.29 0r 29%

c) If the correlation between the stock is 0.00

$=\sqrt{W_1^2\sigma_1^2+W_2^2\sigma_2^2+2W_1W_2\sigma_1\sigma_2*c}$

$=\sqrt{(0.5\times0.33)^2+(0.5\times0.33)^2+(2\times(0.5\times 0.33)\times(0.5\times0.33)\times0.0} \\\\=0.23$

Hence, the volatility of the portfolio is 0.23 0r 23%

d) If the correlation between the stock is -0.50

$=\sqrt{W_1^2\sigma_1^2+W_2^2\sigma_2^2+2W_1W_2\sigma_1\sigma_2*c}$

$=\sqrt{(0.5\times0.33)^2+(0.5\times0.33)^2+(2\times(0.5\times 0.33)\times(0.5\times0.33)\times-0.5} \\\\=0.17$

Hence, the volatility of the portfolio is 0.17 or 17%

e) If the correlation between the stock is -1

$=\sqrt{W_1^2\sigma_1^2+W_2^2\sigma_2^2+2W_1W_2\sigma_1\sigma_2*c}$

$=\sqrt{(0.5\times0.33)^2+(0.5\times0.33)^2+(2\times(0.5\times 0.33)\times(0.5\times0.33)\times-1} \\\\=0$

Hence, the volatility of the portfolio is 0

<h3>In case of b, c, d ,e volatility is less than that of original stock</h3>

Assume that Parker Co. will receive SF200,000 in 360 days. Assume the following interest rates: U.S. Switzerland 360-day borrowi

frez [133]

Answer:

d. $96,914

Explanation:

Parker Co. can execute money market hedge in following steps:

(1) Parker Co. pledges Receivable of SF200,000 to borrow SF190,476 with rate 5% in Switzerland; SF190,476 = SF200,000/ (1+5%)

so it has to pay interest expense of SF9,524 in 360 days. The receivable of SF200,000 is enough for both principal and interest in 360 days.

(2) Then it sells SF190,476 at spot rate $0.48 to get $91,428

(3) Then it deposits $91,428 in US with rate 6% to get back $96,914 in 360 days ; $96,914 = $91,428 * (1+6%)

On August 1, our company purchases $1,000 worth of merchandise inventory on credit with the terms 2/10, n/30. What is the amount

vampirchik [111]

Answer:

a) $1,000

Explanation:

Early Settlement Discount

This form of quotation is common with suppliers offering their customers deferred payment arrangement in a sale contract. Usually, under this arrangement customers are allowed to purchase goods on credit and settle their acccount at a specified later date.

However, to encourage customers to pay up their outstanding earlier than expected, suppliers do offer early settlement discount as incentives to induce prompt payment.

A quotation of 2/10, n/30

This implies that the customer is a given a 30-day period from the date of purchase within which he is expected to settle his account. However, if he does so within the next 10 days of purchase he will be given a 2% discount.

<em>Applying this to the question, the purchase date is August 1, the the latest date for which account is settle to qualify for early settlement discount will be 11 days i.e (1+10) .</em>

Since the payment will be made on August 12, no cash discount will received. Therefore, a payment of gross amount of $1,000 would be credited to the cash account.
