Answer:
I. Consumed energy = 4.5Kwh
II. Total cost = 3375 Dirhams
Explanation:
Given the following data;
Power = 1500W
Time = 3 hours
To find the energy consumption;
Energy = power * time
Substituting into the equation, we have;
Energy consumption = 1500 * 3
Energy consumption = 4500 watt-hour = 4.5Kwh (1 Kilowatts is equal to 1000 watts)
To find the total cost;
Daily cost = Energy consumption * cost
Daily cost = 4.5 * 25
Daily cost = 112.5 Dirham
Therefore, monthly cost = 112.5 * 30
Monthly cost = 3375 Dirham.
