Knowing that you use 275 KWH from 7 a.m. - 7 p.m. and 265 KWH from 7 p.m. - 7 a.m., how much would you pay if you are a NightTimer plan subscriber?

NightTimer Plan Rate: [tex]$0.06445 / KWH

If more than half of power usage is from 7 a.m. - 7 p.m., then you pay the Daytimer rate for all power used between 7 a.m. - 7 p.m.

Options:
A. $[/tex]35.86
B. [tex]$34.80
C. $[/tex]36.89
D. $35.77

To determine the cost if you subscribe to the NightTimer plan, let's follow these steps:

1. Calculate Total Usage:
- For daytime (7 a.m. - 7 p.m.): 275 KWH
- For nighttime (7 p.m. - 7 a.m.): 265 KWH
- Total usage = [tex]\( 275 \text{ KWH} + 265 \text{ KWH} = 540 \text{ KWH} \)[/tex]

2. Identify the Rate for NightTimer Plan:
- The rate for the NightTimer plan is \[tex]$0.06445 per KWH. 3. Calculate Total Cost: - Multiply the total usage (540 KWH) by the NightTimer rate (\$[/tex]0.06445 per KWH).
- Cost = [tex]\( 540 \text{ KWH} \times 0.06445 \text{ USD/KWH} \)[/tex]

4. Round the Result to Two Decimal Places:
- The computed cost is \[tex]$34.80 when rounded to two decimal places. Therefore, as a NightTimer plan subscriber, you would pay \$[/tex]34.80.

The correct answer is \$34.80.
