## Homework Statement

"Fill in the empty columns of the following table"

Table is in the thumbnail

## Homework 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

-E is the EnerGuide energy rating per year

-c is the cost of electricity per kW/h

## 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 I am 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 doesn't 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?**
