Answer:

3rd option: 118 < 0.20p + 18 < 218

Explanation:

The answer is between 118 and 218:

a=answer

118 < a < 218

Now solve fo a:

Since the charge is $18 plus $0.20/kilowatt hour, the result cost is

18 + 0.20p ==> p=kilowatt hour and 0.20p is the cost per kilowatt hour

Hence, a=18 + 0.20p

Hence, the answer is 118 < 18 + 0.20p < 218 ==> plugin 18 + 0.20p for a

118 < 18 + 0.20p < 218 ==> 118 < 0.20p + 18 < 218
