You can put this solution on YOUR website! .
I know that this sort of problems was just solved from 20 to 40 times in this site.
I don't want to repeat these solutions.
I simply took these keywords
"used their sprinklers last summer." algebra.com
and put them into the GOOGLE search.
I got uncounted number of outputs.
I put first five outputs below together with the links.
Probably, I have nothing to add to this material.
You can choose ANY of them and use it as a sample.
