The Scott family and the Phillips family each used their sprinklers last summer. The water output rate for the Scott family's sprinkler was 30L per hour. The water output rate for the Phillips family's sprinkler was 20L per hour. The families used their sprinklers for a combined total of 50 hours, resulting in a total water output of1300L. How long was each sprinkler used?

Best ResponseYou've already chosen the best response.1here are your two equations 20p + 30s = 1300 p + s = 50 multiply the second equation by 20

Best ResponseYou've already chosen the best response.1now we have 20p + 30s = 1300 20p + 20s = 1000 now subtract the two equations.
