Answer:
a) safety stock = z-score x √lead time x standard deviation of demand
z-score for 99.9% = 3.29053
√lead time = √7 = 2.6458
standard deviation of demand = 3
safety stock = 3.29053 x 2.6458 x 3 = 26.12 ≈ 26 soaps
reorder point = lead time demand + safety stock = (7 x 16) + 26 = 138 soaps
EOQ = √[(2 x S x D) / H]
S = order cost = $10
D = annual demand = 16 x 365 = 5,840
H = $0.05
EOQ = √[(2 x $10 x 5,840) / $0.05] = 1,528.40 ≈ 1,528 soaps
b) total order costs per year = (5,840 / 1,528) x $10 = $38.22
total holding costs = (1,528 / 2) x $0.05 = $38.20
total annual ordering and holding costs = $76.42
Answer:
The answer is: C) decreases ; increases
Explanation:
The real cost of borrowing is calculated by adjusting the nominal cost of borrowing by the inflation rate. This means that if the inflation rate increases, then the adjusted real cost of borrowing will decrease.
The inflation rate increases when country´s money supply growth rate outpaces its economic growth. So when the inflation rate increases (lowering the real cost of borrowing), borrowers are more likely to issue bonds, increasing the bond supply.
Answer:
A. the double coincidence of wants problem.
Explanation:
Trade by barter involves the exchange of goods and services for goods and services without the use of money as a medium of exchange. In barter system, there is what we call double coincidence of wants. This is the economic situation whereby both parties holds what the other wants to buy, so they exchange the goods directly. Here, both parties agrees to buy and sell each other commodities. However, if one of the party is not interested in what the other party is offering, it causes a disruption in the trade. This disruption refers to a drawback in the system like the example described in the question.
Here, Andy couldn't make a deal with Danny even tho he wants what Danny is offering. This is because what Danny isn't interested in what Andy is offering. Thus, the double coincidence of want and barter trade can't occur between the two parties.
Answer: a. $1,500
Explanation:
Working capital is calculated by deducting current liabilities from current assets. It is meant to show the operating liquidity of a company within a period.
Working capital = Current assets - Current liabilities
= 5,000 - 3,500
= $1,500
Answer:
4 shirts
Explanation:
Principle of Optimization at the Margin states that the individual maximises utility when consuming a prpduct as long as the marginal benefit exceeds to marginal cost. If marginal cost is greater than the benefit the consumer will find another alternative.
In this instance Maria sees the short as value of $40, while sale price is $21
So when she buys the first shirt her perceived cost is now 40- 5= $35
For the second shirt perceived cost is 35-5= $30
For the third shirt perceived cost is 30-5= 25$
For the fourth shirt it is 25-5= $20
At this stage cost is slightly higher than the benefit and she will stop buying shirts.
