Calculate the cost of using a dishwasher with a 2kW rating for 9 hours a week for 6 weeks? (22c is the cost of one unit)

Step 1: Calculate the total energy consumption in kilowatt-hours (kWh).

The dishwasher has a power rating of 2 kilowatts (kW) and it is used for 9 hours a week for 6 weeks.

So, the total energy consumption is 2 kW * 9 hours/week * 6 weeks = 108 kWh.

Step 2: Convert the cost of one unit to kilowatt-hours (kWh).

One unit of electricity is equal to one kilowatt-hour (kWh). So, the cost of one kWh is 22 cents.

Step 3: Calculate the total cost.

The total cost is the total energy consumption times the cost per kWh.

So, the total cost is 108 kWh * 22 cents/kWh = 2376 cents.

Since 1 dollar is equal to 100 cents, the total cost is 2376 cents / 100 = $23.76.

So, the cost of using the dishwasher for 9 hours a week for 6 weeks is $23.76.
