Light emitting diodes (LED) light bulbs have become required in recent years, but do they make financial sense? Suppose a typica

l 60-watt incandescent light bulb costs $.37 and lasts 1,000 hours. A 15-watt LED, which provides the same light, costs $3.00 and lasts for 12,000 hours. A kilowatt-hour of electricity costs $.113. A kilowatt-hour is 1,000 watts for 1 hour. If you require a return of 10 percent and use a light fixture 500 hours per year, what is the equivalent annual cost of each light bulb?

Answer:

Annual wattage cost of 60 watts is $3.729

Annual LED cost of 60 watts is $0.185

total annual cost = $3.914

Annual wattage cost of 15 watts is $0.935

Annual LED cost of 15 watts is $0.125

total annual cost = $1.06

Explanation:

For the cost of LED and durability

it is require to use a light fixture 500 hours per year

60-watt incandescent light bulb costs $.37 and lasts 1,000 hours. that mean, its last for 2years before buying a new one.

And for a 15-watt LED,  costs $3.00 and lasts for 12,000 hours, thats means it will last for 24 years before purchase of another.

assuming, will are using the 60watts for 24years, a cost of  $.37*12times = $4.44 will be use for buying.

therefore, a 15 watts LED is more cheaper.

For the current charges of LED

for 60watts

if A kilowatt-hour of electricity costs $.113 =

1000 watts = 1hour = $0.113

60 watts  = 1hour  = (60*0.133/1000) = $0.0068

it is said that, the consumption is for 500 hour per year.

therefore, 60watts used per year = 500*0.0068 = $3.39

return of 10% =0.339.

total cost of watts for 500hr for a year = 3.39+0.339 = $3.729

Annual wattage cost of 60 watts is $3.729

Annual LED cost of 60 watts ($0.37/2year) is $0.185

total annual cost = $3.914

for 15 watts

if A kilowatt-hour of electricity costs $.113 =

1000 watts = 1hour = $0.113

15 watts  = 1hour  = (15*0.133/1000) = $0.0017

it is said that, the consumption is for 500 hour per year.

therefore, 15 watts used per year = 500*0.0017 = $0.85

return of 10% =0.085.

total cost of watts for 500hr for a year = 0.85+0.085 = $0.935

Annual wattage cost of 15 watts is $0.935

Annual LED cost of 15 watts ($3/24 years) is $0.125

total annual cost = $1.06

Rus_ich [418]

Answer:

$27,400 and $59,600

Explanation:

The computation of the depreciation expense and the book value using the sum of-the-years'-digits method is shown below:

Depreciation expense is

= (Purchase cost - residual value) × useful life ÷ sum of years

= ($87,000 - $4,800) × 5 years ÷ (5 + 4 + 3 + 2 + 1)

= $27,400

And, the book value is

= Purchase cost - depreciation expense

= $87,000 - $27,400

= $59,600

Your supermarket is trying to determine how many meatloaf dinners should be produced on Monday. The Monday demand for meatloaf d
Alecsey [184]

Answer:

The recommended production quantity is that which maximizes profit.

<em>Quantity 130</em>

<em />

Explanation:

Quantity to produce is the problem here. Remember that this is one of the fundamental questions in the discipline of Economics.

- What to produce?     - For whom to produce?

- How to produce?      - In what quantity?

Possible Production Quantities:

100,  110,  120, and 130

Mean Demand = 100

Standard Deviation = 20

Lowest possible demand = 100 - 20 = 80units

Highest possible demand = 100 + 20 = 120units

<u>* Solve, using the mean demand for each quantity level. Assume also that on every Monday, the minimum possible quantity is what is purchased. That's the safest assumption anyway.</u>

<u />

FOR QUANTITY 100,

Revenue = 7×100 = $700      Direct cost = 2×100 = $200

Indirect cost = 0.6×20 = $12          Total cost = 200 + 12 = $212

PROFIT = 700 - 212 = $488

FOR QUANTITY 110,

Revenue = 7×110 = $770        Direct cost = 2×110 = $220

Indirect cost = 0.6×30 = $18           Total cost = 220 + 18 = $238

PROFIT = 770 - 238 = $532

FOR QUANTITY 120,

Revenue = 7×120 = $840        Direct cost = 2×120 = $240

Indirect cost = 0.6×40 = $24           Total cost = $264

PROFIT = 840 - 264 = $576

FOR QUANTITY 130,

Revenue = 7×130 = $910          Direct cost = 2×130 = $260

Indirect cost = 0.6×50 = $30            Total cost = $290

PROFIT = 910 - 290 = $620

<em>Remember, the base assumption is that only the minimum quantity of 80units is bought each Monday. This is the only way to account for wastage; which costs 0.6 dollar per unit. So, the more the quantity produced, the greater the likelihood of wastage.</em>
