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 (16 times per month).

The question is incomplete, here is the complete question:

How many kWh of energy does a 650-W toaster use in the morning if it is in operation for a total of 6.0min ?

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 (16 times per month).

Express your answer using two significant figures.

$ 0.1 per month

Explanation:

We convert from Watt to kilowatt

650/1000 = 0.65KW

We convert from minutes to hour:

6/60= 0.1 hr

Convert cents to dollars

9/100 = $0.09

Energy cost in KWh= 0.65 × 0.1 × 0.09 ×16= $ 0.1 per month
