The escobar family and the johnson family each used their sprinklers last month. The water output rate for the Escobar family's
MArishka [77]

Answer:

The Escobar family's sprinkler was was used for 14 hours and the Johnson's for 18 hours.

Step-by-step explanation:

I am going to solve this question by a system of equations.

We have that:

x is the number of hours that the Escobar's sprinkler was used.

y is the number of hours that the Johnsons' sprinkler was used.

The families used their sprinklers for a combined total of 32 hours

This means that x + y = 32

Total water output of 1320 gallons.

Escobar 30 gallons a hour, Johnson 50. So

30x + 50y = 1320

From the first equation

x = 32 - y

30x + 50y = 1320

30(32 - y) + 50y = 1320

960 - 30y + 50y = 1320

20y = 360

y = 18

x = 32 - y = 32 - 18 = 14

The Escobar family's sprinkler was was used for 14 hours and the Johnson's for 18 hours.
