a)
To determine: The optimal order quantity of cotton.
a)

Explanation of Solution
Given information:
The monthly demand of each color (red, blue, and white) T-shirts is 3,000 units. 0.5 pounds of cotton is required for each shirt and the purchasing price is given as $2.50. transportation cost by sea is $0.20, the lead time is 2 weeks, ordering cost is $100, and the annual interest rate is 20 percent.
Determine the optimal order quantity of cotton:
Setup cost (S) is given as $100.
Hence, the optimal order quantity of cotton is 4,472 pounds.
b)
To determine: How frequently the firm should order.
b)

Explanation of Solution
Given information:
The monthly demand of each color (red, blue, and white) T-shirts is 3,000 units. 0.5 pounds of cotton is required for each shirt and the purchasing price is given as $2.50. transportation cost by sea is $0.20, the lead time is 2 weeks, ordering cost is $100, and the annual interest rate is 20 percent.
Determine how frequently the firm should order:
Hence, the firm would order 12.08 times a year and 0.99 times (12÷12.08) a month.
c)
To determine: The time the firm should place the order when they need the order on April 1.
c)

Explanation of Solution
Given information:
The monthly demand of each color (red, blue, and white) T-shirts is 3,000 units. 0.5 pounds of cotton is required for each shirt and the purchasing price is given as $2.50. transportation cost by sea is $0.20, the lead time is 2 weeks, ordering cost is $100, and the annual interest rate is 20 percent.
Determine the time the firm should place the order when they need the order on April 1:
It is given that the lead time is 2 weeks. Hence, the firm should order the cotton two weeks before in order to receive it on 1st April. It is about March 15.
d)
To determine: The number of orders to be placed during the next year.
d)

Explanation of Solution
Given information:
The monthly demand of each color (red, blue, and white) T-shirts is 3,000 units. 0.5 pounds of cotton is required for each shirt and the purchasing price is given as $2.50. transportation cost by sea is $0.20, the lead time is 2 weeks, ordering cost is $100, and the annual interest rate is 20 percent.
Determine the number of orders to be placed during the next year:
Hence, the number of orders to be placed during the next year is 12.08.
e)
To determine: The resulting annual holding cost.
e)

Explanation of Solution
Given information:
The monthly demand of each color (red, blue, and white) T-shirts is 3,000 units. 0.5 pounds of cotton is required for each shirt and the purchasing price is given as $2.50. transportation cost by sea is $0.20, the lead time is 2 weeks, ordering cost is $100, and the annual interest rate is 20 percent.
Determine the annual holding cost:
Hence, the annual holding cost is $1,207.
f)
To determine: The resulting annual ordering cost.
f)

Explanation of Solution
Given information:
The monthly demand of each color (red, blue, and white) T-shirts is 3,000 units. 0.5 pounds of cotton is required for each shirt and the purchasing price is given as $2.50. transportation cost by sea is $0.20, the lead time is 2 weeks, ordering cost is $100, and the annual interest rate is 20 percent.
Determine the annual ordering cost:
Hence, the annual ordering cost is $1,208.
g)
To determine: The way the change in annual interest cost would influence the optimal batch size, average inventory, and an annual number of orders.
g)

Explanation of Solution
Given information:
The monthly demand of each color (red, blue, and white) T-shirts is 3,000 units. 0.5 pounds of cotton is required for each shirt and the purchasing price is given as $2.50. transportation cost by sea is $0.20, the lead time is 2 weeks, ordering cost is $100, and the annual interest rate is 20 percent.
Determine the way the change in annual interest cost would influence the optimal batch size, average inventory, and an annual number of orders:
If the annual interest cost reduced to 5 percent, the holding cost would be lower. Hence, the batch size and average inventory would be larger and the number of orders would be smaller.

- Negotiators can gain several benefits from using the strategy of multiple equivalent simultaneous offers. By offering multiple options it reduces the chance of rejection. It also improves the chances of reaching reaching an agreement. By presenting multiple offers, it shows you are flexible. disagree with this post or add on to the postarrow_forwardThe strategy of Multiple Equivalent Simultaneous Offers involves presenting several equally valuable options to the other party during negotiations. This approach benefits negotiators by creating flexibility and increasing the chances of finding a mutually agreeable solution. By offering multiple options, negotiators show that they are open to compromise, which can build trust and make the negotiation process smoother. It also helps avoid getting stuck on one issue, as the other party can choose from several alternatives that meet their needs. In my experience, using MESOs in a work negotiation helped both parties reach an agreement more quickly because each option was carefully thought out to address different needs, and this made it easier for us to settle on one that worked for both sides. This strategy can also reveal what is most important to the other party, helping negotiators understand their priorities better. agree or disagree with the postarrow_forwardExamine the conflicts between improving customer service levels and controlling costs in sales.
