Homework Help: Physics

Posted by Andrea on Wednesday, October 17, 2007 at 4:54pm.

If your last electric bill for sept. was $105. If the average price is 6.5 cents per kw, how many kw did your household use in September?

1kw/.065 = x/$105
.065x=105
x=1615.38 kw

is this correct?

How many Joules is that?
I know that 1W =1Joule/second
1kw=1000W

so 1615.38kw /1000 =1.61538 W
then I get 1.61538W
but how would i get this into joules?
