Question

Jake’s water bill is $23.30 per month plus $2.20 per ccd (hundred cubic feet) of water. What is the maximum number of ccf Jake can use if he wants his bill to be no more than $55.00?

Answer 1

The equation is 23.30 + 2.20x = 55.00

First you subtract 23.3 from 55 which is 31.7 and divide that by 2.2 which is 14.4090909 or 14ccd
