NEED HELP ASAP: WILL MARK BRAINLIEST:
The Hayes family and the Butler family each used their sprinklers last summer. The water output rate for the
Hayes family's sprinkler was 20 L per hour. The water output rate for the Butler family's sprinkler was 15 L
per hour. The families used their sprinklers for a combined total of 50 hours, resulting in a total water output
of 825 L. How long was each sprinkler used?

Answer 1

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.
