Answer: The Hayes family sprinkler was used 15 hrs and the Butler family sprinkler was used 35 hrs.

Step-by-step explanation:

Let the Hayes family sprinkler used = 50 - x hr.

Butler family sprinkler used = x hr.

20 (50 - x) + 15x = 825

1000 - 20x + 15x = 825

175 = 5x

5x = 175

x = 35

The Hayes family sprinkler was used 15 hrs and the Butler family sprinkler was used 35 hrs.
