Question

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


Constant Usage

$0.05324/KWH

Daytimer (Most usage between 7 a.m. – 7 p.m.)

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

$0.05456/KWH

NightTimer (Most usage between 7 p.m. – 7 a.m.)

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

$0.05281/KWH


How much would you have paid on the Constant Usage plan?

Answer 1

To calculate the total cost on the Constant Usage plan, we need to find the total kilowatt-hours (KWH) used and multiply it by the rate of $0.05324/KWH.

1. Total usage:
- Daytime (7 a.m. – 7 p.m.): 245 KWH
- Nighttime (7 p.m. – 7 a.m.): 165 KWH
- Total KWH used = 245 KWH + 165 KWH = 410 KWH

2. Cost calculation:
\[
\text{Total Cost} = \text{Total KWH} \times \text{Rate} = 410 \text{ KWH} \times 0.05324 \text{ USD/KWH}
\]

\[
\text{Total Cost} = 21.83 \text{ USD}
\]

Therefore, on the Constant Usage plan, you would have paid **$21.83**.
