21.6$/month
Step-by-step explanation:
4*150=600watts = 0.6kW
12cents = 0.12$
0.12$*0.6=0.72$
0.72$ * 30days = 21.6$/month
The amount of the electricity cost for 30 days will be 2.16 dollars per month.
What is Algebra?
The analysis of mathematical representations is algebra, and the handling of those symbols is logic.
Lee watches TV for 4 hours per day.
During that time, the TV consumes 150 watts per hour.
The amount of electricity used in a day will be
⇒ 4 × 150
⇒ 600 watts per day
⇒ 0.60 kilowatts per day
Electricity costs (12 cents)/(1 kilowatt-hour). Then the amount of electricity cost in a day will be
⇒ 0.60 × 12 cents
⇒ 0.60 × 0.12 dollars
⇒ 0.072 dollars per day
Then the amount of the electricity cost for 30 days will be
⇒ 0.072 × 30
⇒ 2.16 dollars per month
The amount of the electricity cost for 30 days will be 2.16 dollars per month.
