The table is presented in the thumbnail

Y = E * c

**-Y is the yearly running cost**

-E in the EnerGuide energy rating per year

-c is the cost of electricity per kW/h

-E in the EnerGuide energy rating per year

-c is the cost of electricity per kW/h

## The Attempt at a Solution

Ive done the first 4 columns of the chart and I know how to solve the last one (By using the p = w * t equation) Problem is...I have no idea how to calculate the "estimate of hours of use per week." I've been multiplying and dividing the number of hours per week by about anything I can think of but I am not coming up with the correct answer. If anyone can point me in a direction as to what I need to be calculating the help would be greatly appreciated!

P.S This table was the answer given to us for the example question. The last 2 columns are unfinished on my personal table
