(adsbygoogle = window.adsbygoogle || []).push({}); 1. The problem statement, all variables and given/known data

What does it cost in cents to leave a 1800 Watt electric oven on for 7 hours? Assume that you pay 10 cents for every kilowatt hour which you use.

2. Relevant equations

Well i dont know if im supposed to use P=E/t. i dont know how im supposed to use it

3. The attempt at a solution

Do i not convert 1800 Watts to 1.8 Kilowatts, then multiply 1.8 by 7 hours..which is 12.6 then by .10 cents, which makes the answer 1.26?

It is incorrect though.

Thanks for your help.
