In this case, for the simplicity, let's take the names 1, 2, 3 instead of the fridge name.
00:08
For the first fridge, the power will be 800 watt.
00:15
This corresponding name is mr.
00:18
Bean fridge, that is 800 watt.
00:21
And this is corresponds to 0 .8 kilowatt.
00:26
Therefore, the energy corresponds to this fridge, even is the power.
00:32
0 .8 kilowatt into time is 1 hour that is 0 .0 .0 .8 kilowatt hour so this will be the case of first fridge the second fridge known as super cool fridge that is the power is 780 watt that corresponds to 0 .78 kilowatt and therefore e2 will be the energy will be power into time time is one hour therefore this is similarly as above 0 .78 kilowatt hour and for the third fridge that is ice cold fridge the power is 800 watt for 800 watt we already calculated though this will be the same for this fridge that is e3 will be same as e1 that is 0 .8 kilowatt hour so this will be the energy of the fridge in kilowatt hour units for 1 kilowatt hour, the cost will be given as $18 .4.
01:45
So for first fridge, the e1 is nothing but 0 .8 kilowatt hour.
01:53
Therefore, the total cost will be, the cost of for this will be energy e1 into cost of 1 kilowatt hour, that is $18 .4.
02:05
Dollars and this will be equal to 0 .80 kilowatt hour into 18 .4 dollars so this will be equal to for one hour this is 14 .72 dollars similarly for second fridge e2 is already calculated 0 .78 kilowatt hour therefore the cost for this free the cost energy output cost for this fridge will be 0 .78 kilowatt hour into for one watt hour we have 1 kilowatt hour we have 18 .4 dollars so the cost for this fridge will be 14 .352 dollars similarly for third fridge e3 is 0 .8 kilowatt hour since e3 is same the cost for the fridge for 1 is same as 3.
03:09
The cost must be $14 .72 for third fridge also.
03:16
Now the above charges are calculated for one hour.
03:20
So for 10 years the corresponding charges for each fridges we have to evaluate...
