Answer:

A. Take regular EBS snapshots .

Explanation:

-B is incorrect. It lacks durability of EBS volumes.

-C is incorrect. ECT Instance stores are not durable.

-D is incorrect. Mirroring across EBS volumes is pargely inefficient.

Vlad1618 [11]

Answer:

SUBSTITUTION BIAS

Explanation:

The Consumer Price Index (CPI) is a measure that examines the weighted average of prices of a basket of consumer goods and services, such as transportation, food, and medical care. It is calculated by taking price changes for each item in the predetermined basket of goods and averaging them.

The substitution bias is a weakness in the Consumer Price Index that overstates inflation because it does not account for the substitution effect, when consumers choose to substitute one good for another after its price becomes cheaper than the good they normally buy.

Samantha decides to buy some peppermint because of the 15% inflation on the price of ginger ale, therefore, this situation is most relevant to SUBSTITUTION BIAS in the construction of CPI.

A father wants to save for his eight?year?old son�s college expenses. The son will enter college 10 years from now. An annual am
Ganezh [65]

Answer:

Instructions are listed below

Explanation:

Giving the following information:

The son will enter college 10 years from now. An annual amount of $40,000 in constant dollars will be required to support the son's college expenses for four years.

The future general inflation rate is estimated to be 6% per year, and the market interest rate on the savings account will average 8% compounded annually

A) We need to find the present value for each 40,000-year expense.

Formula= FV/(1+i)^n

1: PV= 40,000/(1.06)^10= 22,335.80

2: PV= 40,000/(1.06)^11= 21,071.50

3: PV= 19,878.77

4: PV= 18,753.56

B) Total final value= 160,000

PV= 160,000/1.06^10= $89,343.16

C) We need to use the following formula:

FV= {A*[(1+i)^n-1]}/i

A= annual deposit

Isolating A:

A= (FV*i)/{[(1+i)^n]-1}

A= (160,000*0.06)/[(1.06^10)-1]= $12,138

In working on a bid for project you have determined that $245,000 of fixed assets will be required and that they will be depreci
mote1985 [20]

Answer:

Question 1:

required investment $245,000

depreciation expense per year = ($245,00 - $23,200) / 5 = $44,360

you will also require $15,000 in working capital

annual cash costs = $68,500

what is the minimum amount of cash sales for accepting the project:

net cash flow₁ = {[(sales revenue - $68,500 - $44,360) x 0.65] + $44,360} / 1.14 = (0.65SR - $28,999) / 1.14 = 0.5702SR - $25,437.72

net cash flow₂ = {[(sales revenue - $68,500 - $44,360) x 0.65] + $44,360} / 1.14² = (0.65SR - $28,999) / 1.14² = 0.5002SR - $22,313.79

net cash flow₃ = {[(sales revenue - $68,500 - $44,360) x 0.65] + $44,360} / 1.14³ = (0.65SR - $28,999) / 1.14³ = 0.4387SR - $19,573.50

net cash flow₄ = {[(sales revenue - $68,500 - $44,360) x 0.65] + $44,360} / 1.14⁴ = (0.65SR - $28,999) / 1.14⁴ = 0.3849SR - $17,169.74

net cash flow₅ = {[(sales revenue - $68,500 - $44,360) x 0.65] + $44,360 + $15,000} / 1.14⁵ = (0.65SR - $13,999) / 1.14⁵ = 0.3376SR - $7,270.64

NPV = -initial outlay + cash flows

NPV = 0

initial outlay = cash flows

$260,000 = 0.5702SR - $25,437.72 + 0.5002SR - $22,313.79 + 0.4387SR - $19,573.50 + 0.3849SR - $17,169.74 + 0.3376SR - $7,270.64

$260,000 = 2.2316SR - $91,765.39

$351,765.39 = 2.2316SR

sales revenue = $351,765.39 / 2.2316 = $157,629.23

the closest answer is B = $155,119, but its NPV will be negative.

<u>so we have to select C = $162,515.75 that results in an NPV = $10,887. </u>

Question 2:

<u>The correct answer is D. return on equity will increase.</u>

If you lower your costs while your sales remain the same, your profits will increase as well as your ROE.
