We are asked to complete the table.
The first column is the appliance that we are analyzing, let's take as an example the "electric fan".
In the second column, we must write the wattage of the appliance, in this case, we have that is this 0.1 kW.
In the third column, we must write the daily use in hours. In this case, we have that it is 7 hours daily.
In the fourth column, we need to write the energy consumed. To do that we multiply the third and fourth columns, like this:
In the fifth column, we must determine the cost of energy consumption. To do that We multiply the energy in kWh by the cost per kWh. We have that the cost is 9.51 per kWh. Therefore, the cost of energy is:
Therefore, the cost to operate is 6.65 pesos daily.
The same procedure is used for the other appliances.
