Jovaughn wants to reduce electricity use at his house so he gives up watching one hour of television a day.if his monthly average electricity bill is reduced from $130 to $40. How much does it cost to watch one hour of television each day?
It costs about $3 per day to watch TV for one hour.
There was an overall decrease of $90. Let's use 30 for the number of days in a month. If we divide 90 by 30, we get a total of $3 per day or hour in this case.
