Subtract the two numbers to find the difference:
200-196 =4
Divide the difference by the estimated number:
4/200 = 0.02
Multiply by 100 to change to percent:
0.02 x 100 = 2%
The answer is 2%
Question one is last option between 8 and 9
Answer:
B. The charge per kilowatt-hour.
Step-by-step explanation:
We have been given that an electric company charges a certain rate per kilowatt-hour of electricity used and an administrative fee of $3.50. The company charged Zhao $63.25 for using 800 kWh of electricity.

Since total bill is $63.25, administrative fee is $3.50 and total use of electricity is 800 kilowatts, therefore, r represents the charge per kilowatt hour and option B is the correct choice.
