Knowing that you use 275 KWH from 7 a. m. β 7 p. m. and 265 KWH from 7 p. m. β 7 a. m., answer the follow question using the chart below.
Constant Usage $0.06624/KWH
Daytimer (Most usage between 7 a. m. β 7 p. m.)
As long as most power used is 7 a. m. β 7 p. m., then you receive a 20% discount on power usage 7 p. m. β 7 a. m.
$0.06831/KWH
NightTimer (Most usage between 7 p. m. β 7 a. m.)
If more than 50% of power usage is outside of 7 p. m. β 7 a. m., then you have to pay the Daytimer rate for all power used 7 a. m. β 7 p. m.
$0.06445/KWH
How much have you paid on the NightTimer plan?
