2000 watts and the family pays $.10 per kilowatt-hour. The appliances runs approximately 30 minutes each day(total together). How much does the family spend
per week to run both these appliances? Show set up with units

Kilowatt-hour = $0.10

Find:

Per week expenses

Computation:

Total uses = 1500 + 2000

Total uses = 3500

Week uses = 3500(30)(7)

Week uses = 735000

Per week expenses = (735000)(0.10)/(1000)

Per week expenses = $73.5
