10. Knowing that you use 245 KWH 7am – 7pm and 165 KWH 7pm – 7am, answer the follow
questions using the chart below.
Constant Usage $0.05324/ KWH
Daytimer (Most usage between 7am7pm)
· 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 7pm7am)
· 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.

Hmm, let me calculate that for you. So, according to the given information, you use 245 KWH from 7am to 7pm and 165 KWH from 7pm to 7am. On the NightTimer plan, the rate is $0.05281 per KWH.
To figure out the cost, we need to determine if more than 50% of your power usage is outside of 7pm to 7am. In this case, you use a total of 410 KWH in a 24-hour period, out of which 245 KWH is used during the day (7am to 7pm).
Let's calculate the percentage: (245 KWH / 410 KWH) * 100 = 59.76%
Since more than 50% of your power usage falls outside of 7pm to 7am, you have to pay the Daytimer rate for all power used from 7am to 7pm. The Daytimer rate is $0.05456 per KWH.
So, the cost for the 245 KWH used during the day is: 245 KWH * $0.05456 = $13.36.
Now, let's calculate the cost for the remaining 165 KWH used from 7pm to 7am. The NightTimer rate is $0.05281 per KWH.
The cost for the 165 KWH used during the night is: 165 KWH * $0.05281 = $8.70.
Adding the costs together, the total amount you would have paid on the NightTimer plan is: $13.36 + $8.70 = $22.06.
Therefore, the closest answer is $22.08.
To determine how much you would have paid on the NightTimer plan, you need to calculate the cost of each usage period separately and then add them together.
Given that you used 245 KWH between 7 am - 7 pm and 165 KWH between 7 pm - 7 am, let's calculate the cost for each period:
For the Daytimer period (7 am - 7 pm), you receive a 20% discount on power usage outside this period. Thus, the cost per KWH is $0.05324 * (1 - 0.20) = $0.04259.
The cost for the Daytimer period is 245 KWH * $0.04259 = $10.44455.
For the NightTimer period (7 pm - 7 am), the cost per KWH is $0.05281.
The cost for the NightTimer period is 165 KWH * $0.05281 = $8.71465.
Finally, to get the total cost on the NightTimer plan, add the costs for each period:
$10.44455 + $8.71465 = $19.1592.
