Jake's water bill is $24.40 per month plus $2.20 per ccf (hundred cubic feet) of water. What is the maximum number of ccf Jake c
siniylev [52]

Answer:the maximum number of ccf Jake can use if he wants his bill to be no more than $58.00 is $15.3

Step-by-step explanation:

Let x represent the number of ccf of water that Jake uses in a month.

Jake's water bill is $24.40 per month plus $2.20 per ccf (hundred cubic feet) of water. This means that if she uses x ccf of water in a month, her total water bill would be

24.40 + 2.2x

Therefore, the maximum number of ccf Jake can use if he wants his bill to be no more than $58.00 would be

24.40 + 2.2x ≤ 58

2.2x ≤ 58 - 24.4

2.2x ≤ 33.6

x ≤ 33.6/2.2

x ≤ 15.3
