In summary, Mrs. Keely has 3 small children and runs her washing machine once every day, including weekends. It is assumed that she runs it four times a week, and no input cost is given to calculate the output cost for a 2kWh machine per year.

"She runs her washing machine every day" must mean once every day. :wink:

(it can't be less, and if it was more, the question would say so)

(if it said "she buys an apple every day", would you worry that it might mean that she buys several apples a day?)

you're going to have a hard time figuring out an output cost for this question since no input cost is given
 

What factors contribute to the cost of running Mrs Keely's washing machine per year?

The cost of running a washing machine can be affected by several factors, including the frequency of use, the type and efficiency of the machine, the cost of electricity in the area, and any additional features or settings that may increase energy consumption.

How can Mrs Keely reduce the cost of running her washing machine per year?

Mrs Keely can reduce the cost of running her washing machine by using it less frequently, choosing a more energy-efficient machine, using cold water when possible, and avoiding using additional features that may consume more energy.

What is the average cost of running a washing machine per year?

The average cost of running a washing machine per year can vary depending on the factors mentioned above. However, a study by Energy Star found that the average cost for running a washing machine is around $14 per year.

How can I calculate the cost of running my washing machine per year?

To calculate the cost of running your washing machine per year, you can start by determining the cost of electricity per kWh in your area. Then, estimate the average amount of energy your machine uses per load and multiply it by the number of loads per week. Finally, multiply this number by 52 (weeks in a year) and then by the cost per kWh to get an estimate of the annual cost.

What are some tips for reducing the cost of running a washing machine?

In addition to the tips mentioned above, other ways to reduce the cost of running a washing machine include using a shorter wash cycle, avoiding overloading the machine, and regularly cleaning and maintaining the machine to ensure it is running efficiently.
