It seems hard to justify spending $4.00 for a compact fluorescent lightbulb when an ordinary incandescent lightbulb costs 50 ¢.

To see if this makes sense, compare a 60 W incandescent bulb lasting 1000 hours to a 15 W compact fluorescent bulb having a lifetime of 10,000 hours. Both bulbs produce the same amount of visible light and are interchangeable. If electricity costs $0.10/kWh, what is the cost - purchase plus energy - to obtain 10,000 hours of light from each type of bulb? This is called the life-cycle cost.

Answer:

to obtain 10,000 hours of light you would need:

option 1)

10 incandescent light bulbs costing $0.50 each = $5

this incandescent light bulbs will consume 60 x 10,000 = 60,000 watts or 60 kWh = 60 x $0.10 = $6 in electricity

total costs using incandescent light bulbs = $5 + $6 = $11

option 2)

1 fluorescent light bulb = $4

this fluorescent light bulb will consume 15 x 10,000 = 15,000 watts or 15 kWh = 15 x $0.10 = $1.50

total costs using fluorescent light bulbs = $4 + $1.50 = $5.50

Answer:

Davis Florist

a. (Anita, Jerome) __Jerome____ absolute advantage in floral arrangements. __Jerome____ (Anita, Jerome) has an absolute advantage in deliveries.

b. Anita’s opportunity cost of making one floral arrangement is ___0.75__

( 1.33, 0.75, .33, 3) deliveries. Anita’s opportunity cost of making one delivery is __1.33_ (1.33, 0.75, .33, 3) floral arrangements.

c. Jerome’s opportunity cost of making one floral arrangement is ___0.33__(.75,3,1.33..33) deliveries. Jerome’s opportunity cost of making one delivery is 3 (3, 1.33, .75, .33) floral arrangements.

d. (Jerome, Anita)_Jerome____ has a comparative advantage in floral arrangements. (Jerome, Anita)__Anita___ has a comparative advantage in deliveries.

e. Suppose that, initially, both Jerome and Anita spend four hours each day doing floral arrangements and two hours each day doing deliveries. Now suppose they change their tasks, so that each individual does nothing but the task in which she or he has a comparative advantage. How many more floral arrangements and deliveries could they produce each day?

____4_____ additional floral arrangements

____5____ additional deliveries

Explanation:

a) Data and Calculations:

Time it takes Anita to finish one floral arrangement = 30 minutes

Time it takes Anita to make a delivery = 40 minutes

Time it takes Jerome to finish one floral arrangement = 10 minutes

Time it takes Jerome to make a delivery = 30 minutes

b) Absolute Advantage: Jerome will finish 3 floral arrangements (30/10), whereas Anita can only finish 1 in 30 minutes.

c) Anita's opportunity cost is the time it will take her to make a delivery using the same time it takes her to finish one floral arrangement.  In 30 minutes time, she can only make (30/40) 0.75 deliveries.  Using 40 minutes of making a delivery, she can finish 1.33 (40/30) floral arrangements.

d) Anita's comparative advantage in making deliveries is based on her opportunity cost when compared with Jerome's opportunity cost of making deliveries.

                                          Floral            Delivery      Total hours

                                    Arrangement

e) Total time spent by

   Anita                                4 hrs              2 hrs          6 hrs

   Jerome                            4 hrs              2 hrs          6 hrs

                                                        Anita                  Jerome      Total

Number of floral arrangements     8 (240/30)        24 (240/10)   32

Number of deliveries                      3 (120/40)           4 (120/30)     7

                                                         Anita                  Jerome

Number of floral arrangements       0                       36 (360/10)  36

Number of deliveries                        12 (360/30)        0                 12

Minor company installs a machine in its factory at the beginning of the year at a cost of $135,000. the machine's useful life is
sveticcg [70]

To determine what the depreciation of an asset using straight line method, the formula to be used is:

(Initial cost of machine – salvage value) divided by estimated useful life


So in this problem:

Initial Cost - $135000

Salvage Value – $15000

Estimated Useful Life – 5 years

Plug that in the formula


Annual depreciation = ($135000 - $15000) / 5

= $120000/ 5

= $24,000


The first year depreciation for the machine is $24000 because the company bought it in the beginning of the year. (So there is no need to divide this by 12 months)

To record this:

Depreciation Expense $24000

<span>          Accumulated Depreciation $24000</span>

Dmitriy789 [7]

Answer:

$14,000

Explanation:

Sale made = Accounts Receivable on 30 June + Collections of accounts - Accounts Receivable on 1 June

= $15,000 + $25,000 - $10,000

= $30,000

Cost of goods sold = Sales made ÷ rate of mark-up on cost

= $30,000 ÷ 150% × 100%

= $20,000

Estimated cost of the June 30 inventory = Inventory Balance on June 1 +  Purchases made during June -  Cost of goods sold

= $18,000 + $16,000 - $20,000

= $34,000 - $20,000

= $14,000
