Knowing that you use 275 KWH from 7am-7pm and 265 KWH 7pm-7am, answer the question.

How much have you paid on the NightTImer plan?
NightTimer Plan: If more than 50% of usage is outside of 7pm-7am, then you have to pay the DayTimer rate for all power used between 7am-7pm. $0.06445/KWH

DayTimer: As long as most power used if from 7am-7pm, then you receive a 20% discount on power usage between 7pm-7am.
$0.06831/KWH

What you need to do right here is to do a Fraction of total power used at night: f = 265 / 265+275 If   f >0.5 then use Daytime Plan.
Use NightTimer plan otherwise which is f > 0.5
Remember that Both Daytime and Nightimer plans say if most of the power used is between 7am-7pm then used the rates. Hope this is bery useful
