Assume that the hourly cost to operate a commercial airplane follows the normal distribution with a mean of $5,793 per hour and

AfilCa [17]

Answer:

x1 = 4891.294

Explanation:

given data

mean μ = $5,793

standard deviation σ = $439

solution

we know here that

P(x < x1 ) = 0.02 .................1

so

$P(\frac{x-\mu }{\sigma } < \frac{x1-\mu }{\sigma }) = 0.02$

so

$P(z < \frac{x1-\mu }{\sigma }) = 0.02$

$\frac{x1-\mu }{\sigma }$ = invNorm(0.02)

so

x1 = μ + σ × invNorm(0.02) .....................2

we use here table for invNorm(0.02) and put value in eq 2

x1 = 5793 + 439 × (-2.054 )

x1 = 4891.294

Received pesos = Exchange value of one U.S dollar for Mexican pesos ÷ Exchange value of one U.S dollar for Mexican pesos

= 10.875 ÷ 6.205

= 1.753 pesos/krone

It shows a relationship between the Exchange value of one U.S dollar for Mexican pesos and the Exchange value of one U.S dollar for Mexican pesos so that per pesos/krone can come

Cono-Cool air conditioners cost $350 to purchase, result in electricity bills of $160 per year, and last for 5 years. Luxury Air

tatuchka [14]

Answer:

a) The equivalent annual costs of the Econo-Cool models= $436.50

b) The equivalent annual costs of the of Luxury Air models = $515

c)Econo-cool model

d 1 .(i) $464.15

(ii) $597.95

d 2 . Econo-cool model

Explanation:

a) Econo-cool model

Purchase price= $350

Discount =21%

Electricity bill= $160 per year

Annual cost per year will be

$350 * 79/100 =$276.50 ------after applying the 21% discount

$276.50+$160 =$436.50 -------after adding electricity cost per year

The equivalent annual costs of the Econo-Cool models= $436.50

b) Luxury Air Models

Purchase price at the shop=$550

Discount =21%

Buying price =79/100*$500 = $395

Electricity cost = $120 per year

Annual cost = $395+$120 =$515

The equivalent annual costs of the of Luxury Air models = $515

c) The Econo-cool model

d (1) Econo-cool model

$350 *110/100 =$ 385 -----due to inflation

Apply the discount = 385*79/100 =$304.15

Add the cost of electricity = $304.15+$160 =$464.15

For Luxury Air model

$550*110/100 =$605

Apply the discount = $605*79/100 =$477.95

Add electricity bill = $477.95 +$120 =$597.95

Phillip Witt, president of Witt Input Devices, wishes to create a portfolio of local suppliers for his new line of keyboards.

kirill115 [55]

Answer:

Based on the EMV value, the best choice is to use Two suppliers

Explanation:

Is necessary to consider different amount of suppliers and evaluate the cost. We will choose the number of suppliers which offers a lower cost.

EMV1 = cost of shutdown*super event risk + cost of shutdown*unique event risk + cost of managing supplier = 480000*.02 + 480000*0.05+16000 = 9600 + 24000 + 16000 = $ 49600

EMV2 = cost of shutdown*super event risk + cost of shutdown*unique event risk of each supplier*unique event risk of each supplier + cost of managing 2 suppliers = 480000*.02 + 480000*0.05*.05+16000*2 = 9600 + 1200 + 16000*2 = $ 42800

EMV3 = cost of shutdown*super event risk + cost of managing 3 suppliers = 480000*.02 + 480000*0.05*.05+16000*2 = 9600 + 16000*3 = $ 57600

Based on the EMV value, the best choice is to use Two suppliers

On January 1, Year 1, Manning Company granted 97,000 stock options to certain executives. The options are exercisable no sooner

umka21 [38]

Answer:

$77,600

Explanation:

Total value of compensation expenses:

= No. of options granted × Fair of value options

= 97,000 × $4

= $388,000

Compensation expenses should be recognized per year:

= Total value of compensation expenses ÷ Excercisable time

= $388,000 ÷ 3

= $129,333.33

Expenses recognized in year 1 = $129,333.33

Due to unexpected turnover 20% of the options are forfeited,

Annual compensation = $388,000 × 80%

= $310,400

Annual compensation in year 2:

= Accumulated compensation expenses in year 2 - Expenses recognized in year 1

= [$310,400 × (2/3)] - $129,333.33

= $206,933.33 - $129,333.33

= $77,600
