Question
Marcella runs the space heater in her office 8 hours per day durin gthe months of December (30 days) and January (31 days). It has a power rating of 1200 watts. if the residential rate is 10.8 cent per kilowatt hour, how much does it cost Marcella to run her space heater during these two months
Expert Solution
Step 1
Given,
Runtime of the heater = 8 hours per day.
Total number of days= 30+31 = 61 days
Power rating = 1200 watts
= 1200/1000 = 1.2 kwh
Residential rate= 10.8 cent per kwh
Step by step
