What is the procedure?

Procedure:

1. Find the electricity consumption for one boil.
2. Multiply the result of step 1 by the cost of 1 kWh (ask your parents) to get the cost of electricity for one boil.
3. Multiply the result of step 2 by the number of boils per day to get the cost of electricity consumption per day.
4. Multiply the result of step 3 by 30 days to get the approximate cost of electricity consumption per month.
