Answer:

cost to run the LED bulb for one year if it runs for 3 hours a day is $3.50  

Explanation:

given data

power = 16 W

cost of electricity = $0.20 per kilowatt-hour

time =  3 hours a day.

solution

we get here energy consumption is express as

E = Power × time

E = (16) × (365 × 3)

E =  17520 Wh

E =  17.52 kWh

and

cost of operation = E × cost of electricity    .........1

cost of operation =  17.52 × $0.20

cost of operation = $3.50

so cost to run the LED bulb for one year if it runs for 3 hours a day is $3.50

Varvara68 [4.7K]

Bulldog, Inc., has sold Australian dollar put options at a premium of $.02 per unit, and an exercise price of $.89 per unit. It
Reika [66]

Answer:

Explanation:

At $0.86

$0.86<$0.89

The buyer of the call option will not exercise the option. Net profit will be equal to the premium paid per unit = $0.02/unit.

At $0.87

$0.87<$0.89

The buyer of the call option will still not exercise the option. Therefore, net profit will be equal to the premium paid per unit = $0.02 unit. So net profit = $0.02/unit

At $0.88

$0.88<$0.89

The buyer of the call option will still not exercise the option. Net profit will be equal to the premium paid per unit = $0.02 unit. So net profit = $0.02/unit

At $0.89

$0.89=$0.89

The buyer of the call option will still not exercise the option. Net profit will be equal to the premium paid per unit = $0.02/unit.

At $0.91

The buyer will exercise the option and the net loss to Bulldog Inc will be 0.02/unit  ($0.91-$0.89)

So there is no profit and no loss because this is offset by the call premium

Profit = -0.02 (loss on exercise) + 0.02 (call premium) = $0/unit

At $0.92

The buyer will exercise the option. The net loss to Bulldog Inc will be $0.03/unit  ($0.92-$0.89)

Loss= -0.03 (loss on exercise) + 0.02 (call premium) = -$0.01/unit

atroni [7]

Answer:

cost of goods sold is $197,800

ending inventory is $55,000

Explanation:

LIFO System is an Inventory Management Method that sells the Recent Inventory Acquired First followed by older Inventory.

<u><em>Cost of Goods Sold</em></u>

March 14 = (1,380×$62) = $85,560

August 31 = (1,130×$80) =  $90,400

                 =  (70×$62)    =   $ 4,340

                 = (350×$50)   =  $ 17,500

Total                                =  $197,800

<em><u>Closing Inventory</u></em>

(1,100×$50) = $55,000
