conversations.value: I'm stuck on this math problem: Kim's TV uses 125 watts of electricity per hour.  She runs it for 4 hours a day.  If electricity cost 14 cents per kw/h how many cents does her TV cost to run for a week?
  Can you help?

conversations.value: She uses 4 hours/day * 125 watts/hour=500 watt hours/day
  That means she uses 500 watt hours/day * 7 days/week = 3500 watt hours/week
  This is 3500 watt hours / 1000 watts/kw = 3.5 kw hours
  So her TV cost 3.5 kw hours/week * $0.14/kw hour = $0.49/week
