Rudiy27

Answer:

$163,104

Explanation:

loan principal = monthly payment x PV annuity factor

monthly payment = $950

PV annuity factor, 0.4583%, 240 periods = 145.3726

loan principal = $950 x 145.3726 = $138,104

the price of the house = down payment + loan = $25,000 + $138,104 = $163,104

Svet_ta [14]

Answer: Newton Grocers

Explanation: Riley Market, Newton Grocers, and Barlow Pantry are grocery stores. During physical inventory, Riley remains fully open, while Newton closes until the count is complete. Barlow falls between the others, selling only a small selection of essential items such as milk and bread during inventory. Newton Grocers would have the most accurate inventory because Newton doesn't close until the count is complete.

15. Rick Barr Inc. is considering a new product line that has expected sales of $500,000 per year for each of the next 5 years.

ozzi

Answer: A.) $250,900

Explanation:

Given the following ;

Working Capital = $10,000

Salvage value = $80,000

Cost of equipment = 800,000

Tax rate = 35%

Number of useful years = 5 years

The formula for cash flow is = EBIT * (1 - tax rate) + Depreciation + Salvage Value + Working Capital released

Depreciation = (cost - Salvage value) ÷ Number of useful years

Depreciation = $(800,000 - 80,000)/5

Depreciation = $720,000÷5 = $144,000

EBIT = Sales - Variable costs - Fixed costs - Depreciation

EBIT = $500,000 - $230,000 - $100,000 - $144,000

EBIT = $26,000

Cash flow = $26,000(1 - 0.35) +$144,000 + $80,000 + $10,000

Cashflow = $250,900

Suppose the elasticity of demand for your parking lot spaces, which are located in a downtown business district, is –1.8, and th

Ipatiy [6.2K]

Answer:

Elastic

DECREASED

Explanation:

The price elasticity is elastic. Demand is price elastic if the absolute value of coefficient of elasticity is greater than 1.

When demand is elastic, it means that quantity demanded is sensitive to changes in price. A small change in price would lead to a greater change in quantity demanded.

Because the parking lot has been operating below its full capacity and marginal cost is zero, the optimal strategy is to reduce price so that quantity demanded would increase.

The rates of return on Cherry Jalopies, Inc., stock over the last five years were 16 percent, 11 percent, −1 percent, 6 percent,

Anastasy [175]

Answer:

Cherry:

S = 0.01652

standard deviation = 0.128530152

Straw:

S =0.0478

And the standard deviation = 0.218632111

Explanation:

<u>Cherry Jalopies:</u>

variance:

∑ (n1 - median)2

First we calcualte the median:

(0.16 + 0.11 - 0.01 + 0.06 + 0.11)/5 = 0.086

Then we calculate the variance:

which is each the sum of return minus the median squared

$(0.16-0.086)^{2} +(0.11-0.086)^{2} +(-0.01-0.086)^{2} +(0.06-0.086)^{2} +(0.11-0.086)^{2}$

S = 0.01652

standard deviation: √S = √0.01652 = 0.128530152

<u>Straw</u>

we do the same procedure:

(0.16+0.23 -0.06+0.06+0.11)/5 = 0.1

Then we do the variance:

0.0478

And the standard deviation:√S = √0.0478 = 0.218632111
