Answer:
Explanation:
Annual demand (D) = 20000 units
Number of days per year = 250
Demand rate(d) = D/number of days per year = 20000/250 = 80 units
Production rate(p) = 655 units
Set up cost(S) = $1800
Holding cost (H) = $1.50
A) Optimum run size(Q) = sqrt of {2DS / H [1-(d/p)]}
= sqrt of {(2x20000x1800) /1.50[1-(80/655)]}
= Sqrt of [7200000/1.50(1-0.1221) ]
= sqrt of [72000000/(1.50 x 0.8779)]
= sqrt of (7200000/1.31685)
= Sqrt of 5467593.1199
= 2338 units
b) Maximum inventory ( I - max) = (Q/p) (p-d) = (2338/655)(655-80) = 3.5695 x 575 = 2052.46 or rounded off to 2052 units
Average inventory = I-max/2 = 2052/2 = 1026 units
C) Number of production setups per year = D/Q = 20000/2338 = 8.55 or rounded up to 6
d) optimal length of production run = optimal run size /production rate = 2338/655 = 3.56 or rounded up to 4 days
Answer:
B. Taking a friend to lunch in return of a favor
Explanation:
Barter System is direct commodity/ service to commodity/service exchange , without using money as an intermediary exchange medium . It is also called C to C exchange .
Eg : Two farmers exchanging their wheat & rice , A teacher teaching grocers' child in exchange of groceries from him .
So : A. Simple Investment , C. Money Purchase , D. Money Denomination exchange - neither are examples of Barter System .
B . Paying off a friend's favour in exchange of a service (being service-service exchange) is a relatable example.
Answer:
The correct answer is: "People are rational".
Explanation:
Economics is the study of people's rational options when faced with scarcity and uncertainty, and that happens to all of us. The problem is that people are hardly rational, because our nature often acts against our economic interests.
Not long ago and until today, the work is done during the day, that is, Monday through Friday; A reality for most people. However, much of the economic activity, both ours and the entire world, operates 24/7. Today, millions of workers have unpredictable schedules. This is especially common in jobs related to services and retail sales. For example, many chain stores use personnel algorithms with traffic and apparently this makes sense, but shareholders always expect efficient efforts to maximize profits. If not, however difficult it is, particularly for workers, to get another job.
Answer: b. Its quick ratio decreases.
Explanation:
The Quick ratio is calculated net of inventory to determine if a company can cover its current liabilities with its more liquid current assets. The formula is to subtract Inventory from the Current Assets and then divided that by the Currency liabilities.
The Quick ratio will be less than before because the number of current assets will not change but the amount of current liabilities will change as the goods were purchased on credit. With a larger denominator, the resultant ratio will be less than before.
