Knowing that you use 245 KWH from 7 a. m. – 7 p. m. and 165 KWH from 7 p. m. – 7 a. m., answer the following question using the chart below.

Constant Usage $0.05324/ KWH
Daytimer (Most usage between 7am-7pm)

As long as most power used is 7am – 7pm, then you receive a 20% discount on power usage 7pm – 7am.

$0.05456/ KWH
NightTimer (Most usage between 7pm-7am)

If more than 50% of power usage is outside of 7pm – 7am, then you have to pay the Daytimer rate for all power used 7am – 7pm.

$0.05281/ KWH

How much would you have paid on the NightTimer plan?
