1. The problem statement, all variables and given/known data "Fill in the empty columns of the following table" Table is in the thumbnail 2. Relevant equations work = force / distance power = work / time Y = E * c -Y is the yearly running cost -E is the EnerGuide energy rating per year -c is the cost of electricity per kW/h 3. The attempt at a solution I have already filled in the first 2 blank rows on the table. The E per week is 5.08kWh/week and 17.5kWh/week for the running yearly cost Y it is $0.30/week and $1.05/week This is where im stuck. I have no idea how to fill out the last 2 columns with the information I currently have. I thought I would need to divide and or multiply a number by 168 (number of hours in a week) but that doesnt seem to do any good. Could someone point me in the direction as to what I need to calculate in order to find the estimated hours of use per week?
