Answer:
A) 200 units
Explanation:
mean daily demand = 20 calculators
standard deviation = 4 calculators
lead time = 9 days
z-critical value (for 95% in-stock probability) = 1.96
normal consumption during lead-time:
= mean demand × lead time
= 20 × 9
= 180 calculators
safety stock = z × SD × √L
= 1.96 × 4 × √9
= 1.96 × 4 × 3
= 23.52 calculators
reorder point = normal consumption + safety stock
= 180 + 23.52
= 203.52 calculators
Answer:
a) The expected return of equally weighed portfolio is 14.23%
b) The expected return of equally weighed portfolio is 16.45%, hence Variance = 1.596457%
Explanation:
See workings of a and b attached in a form of spreadsheet.
Answer:
a) a monetary unit for measuring and comparing the relative values of goods.
Explanation:
In the case when the economist said that money could be treated as the store of value so this means that it represent one of the functions of money which can be stored and retrieve later onwards
Also it is a monetary unit that could be used for measuring and also compared the goods value
Therefore the option a is correct
Answer:
(a) C(x) = 9500 + 55x
(b) R(x) = 90x
(c) P(x) = 35x - 9500
(d) C(240) = $22,700
All functions are measured in $.
Explanation:
The total revenue of an entity is a function of the number of units sold and the selling price per unit. The total cost is a function of the fixed cost and the variable cost (which is also a function of the units produced/sold). Profit is a function of sales and cost.
Given that monthly;
fixed costs = $9500
variable costs = $55 per unit
Selling price = $90 per unit
Where x is the number of units
total costs C(x) in $ = 9500 + 55x
total revenue R(x) in $ = 90x
profit P(x) in $ = 90x - (9500 + 55x)
= 35x - 9500
C(240) = 9500 + 55(240)
= $22,700
TRUE. A company might conduct full-scale practice drills, including closing a building and working from a remote location, in order to test its contingency plans
