Answer 1

It is given in the question that

Emily’s last water bill listed a previous reading of 7,123 ccf and a present reading of 7,171 ccf. Her water company charges $0.73 per ccf of water.

Therefore number of ccf  is

$= 7171-7123 = 48ccf$

And company charges $0.73 per ccf.

So for 48 ccf, company charges

$= 0.73*48 = 35.04$

And that's the required answer .
