2 part problem
How many kWh of energy does a 650-W toaster use in the morning if it is in operation for a total of 20min?
At a cost of 9.0 cents/kWh, estimate how much this would add to your monthly electric energy bill if you made toast four mornings per week.
None really, just a lot of conversions.
The Attempt at a Solution
650 W = .650 kW
0.650 kW(.33 hr) = 0.2145 khW
(0.2154 kWh)(5.28 hr)(0.09 kWh) = .10
I know that sounds really low but I'm unsure of my error.
Here's how I found 5.28 if it matters.
(0.33 hr)(16 times/month) = 5.28 hr
