A mechanical engineer must recommend an A/C system to a commercial building owner. The owner uses and MARR of 6%, but is not sur

e how long he will own the building. A conventional split system has a design life of 10 years, a cost of $52,000, and annual operating costs of $15,000. A chilled water system has an initial cost of $75,000 and annual operating costs of $14,000. Assuming each unit has no salvage value and will be identically replaced for the life of the building, determine how long the chilled water system needs to last for it to be the best choice (i.e. determine the break even useful life for the chilled water system). Express your answer in years to the nearest whole year.

Answer:

12 years

Explanation:

The chilled water system lasts for in line with the building. To calculate break even useful life of chilled water we assume no salvage value. The company uses MARR of 6% . The conventional system costs $52,000 and annual operating cost is $15,000. We can calculated the useful life by adding the system cost and its operating cost with multiplying minimum acceptable rate of return.

$52,000 * A/P (6%, 10) + $15,000 = 12 years.

quester [9]

Answer:

Cost of goods sold on April 25 is $13.80 and the inventory balance is $55.20

Explanation:

Data given:total unit

Cost of purchase with  data;

Date                  Amount

April 5                 $10

April 10                $12

April 15                $14

April 20                 $16

April 22                 $17

Total cost             69    

Average cost = total cost /total quantity

                       = 69/5

                       =13.8

The cost of the ending inventory is given on the balance sheet below

Date      Purchases              Cost of            Inventory Bal.   Avg Cost

                                            goods sold

April 5   $10* 1 unit= $10                -                        $10               10/1 = $10

April  10  $12* 1 unit=$12               -               10+ 12 = 22            22/2 = 11

April  15   $14* 1 unit=$14                  -           22+14 =36              36/3 = 12

April 20   $16* 1 unit= $16                  -          36 +16 =52            52/4 = 13

April 22    $17* 1 unit = $17                 -          52+17 =69            69/5 = 13.8

April 25             -           1 unit*13.8 = 13.80      69 - 13.8 = 55.20

inysia [295]

Answer:

<u>Part a:  What will be the equilabrium price that Dumphy and Funke will charge?</u>

Answer: Price charged = $30

<u>Part b: What are the profits for Dumphy and Funke at the equilibrium price?</u>

Answer: Profit on equilibrium price = $0

<u>Part c: What type of competition would Funke and Dumphy likely engage in after the decrease in demand?</u>

Answer: Price competition

Explanation:

<u>Part a:  What will be the equilabrium price that Dumphy and Funke will charge?</u>

Answer:

Price charged by each of the artists will be equal to their marginal cost.

Thus, equilibrium P = MC = $30.

<u>Part b: What are the profits for Dumphy and Funke at the equilibrium price?</u>

Answer:

Equilibrium profits will be 0 at the equilibrium because price charged is equal to MC, leading to no profits.

<u>Part c: What type of competition would Funke and Dumphy likely engage in after the decrease in demand?</u>

Answer:

Price competition - as changes in price will lead to changes in demand and thus sales

Sergeeva-Olga [200]

Answer: 5,882.5‬ hours

Explanation:

Cumulative Labor Hours to be planned for = Cumulative factor * Time of first unit

Cumulative Factor = Average learning rate for Number of units.

Learning rate from unit 1 to 2 = Labor hours required for 2nd unit / Labor Units required for 1st unit

= 2,250/2,500

= 0.9

Learning rate from unit 2 to 3 = Labor hours required for 3rd unit / Labor Units required for 2nd unit

= 2,120/2,250

= 0.94

Average learning rate = (0.9 + 0.94) / 2

= 0.9

= 90%

There are 6 units in total including the first units checked and the additional 3 units.

Cumulative factor for 6 units at 90% from the table is 5.101.

Cumulative labor hours = 5.101 * 2,500

= 12,752.5‬ hours

The time for the Addiotnal 3 units is;

= Cumulative time for all units - time for the first 3 units

= 12,752.5 - 2,500 - 2,250 - 2,120

= 5,882.5‬ hours

Granfield Company has a piece of manufacturing equipment with a book value of $44,000 and a remaining useful life of four years.
Troyanec [42]

Answer:

$26,000

Explanation:

The calculation of Net increase or decrease in income on replacement is shown below:-

Net savings in Variable cost for 4 years = Variable manufacturing costs × Life

= $19,800 × 4

= $79,200

Net Investment to be made in New machine = Initial investment of new machine - Traded in value of old machine

= $128,000 - $22,800

= $105,200

Net financial disadvantage of replacement = Net savings in Variable cost for 4 years - Net Investment to be made in New machine

= $79,200 - $105,200

= $26,000

So, for computing the net financial disadvantage of replacement we simply applied the above formula.
