I have a big home theatre and right now it costs about $500 dollars a month due to all the speakers, and everyone in my family use it all day, how could I reduce the bill but still have a home theatre?

I would choose B, I think it’s just easier to get rid of some speakers and keep the power bill that way, then having to rewire and set up another room just for the power bill to be smaller. If we remove all the useless speakers and keep two good ones, then it will help us get a smaller power bill and we won’t have to pay $500 and we get to keep the big theatre room. It will still be a room that anyone can use in their free time, and it’ll cost less.

 If I run my 80-watt lights for 2 hours a day, what is my power bill for the year? 

a) What is the yearly bill

b)how can i decrease my bill? 

 A) Half the time and watts. b) Half the time. Why is this the better option? 

My current power bill for the year is $7.2. I can decrease it by halving the time and watts. If I do this, my power bill will be $2.16. If I only halved the time, my power bill would be $3.6. By halving the time and watts, I decreased my power bill by 1/3.
