Answer:
Explanation:
Present value is calculated as the discounted sum of either a fixed amount or a series of payments in the future, at a given interest rates.
For example, at an interest of 5%, $100 in 10 years will be valued at $100 / 1.05^10 = $61.39 today
Answer:
Proposal A
3.75 years
Proposal B
3.375 years
Explanation:
<u>Proposal A</u>
Payback = 3.75 years
Year Cash Inflow Initial Investment Balance Year Count
0 0 1,050,000
1 $280,000 770,000 1
2 $280,000 490,000 2
3 $280,000 210,000 3
4 $280,000 0 *3.75
* 1050,0000 / 280,000 = 3.75 years
<u>Proposal B</u>
Payback = 3.375 years
Year Cash Inflow Initial Investment Balance Year Count
0 0 1,050,000
1 $350,000 700,000 1
2 $3150,000 385,000 2
3 $280,000 105,000 3
4 $280,000 0 *3.375
* ( 3 + ( 105,000 / 280,000 ) ) = 3.75 years
Answer:
d) Mary, who was laid off last year and who was looking for a full-time job until last month
Explanation:
In the United States, a discouraged worker is defined as a person not in the labor force who wants and is available for a job and who has looked for work sometime in the past 12 months (or since the end of his or her last job if a job was held within the past 12 months), but who is not currently looking because of real or perceived poor employment prospects.
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
