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
Total water output of 1320 gallons.
Escobar 30 gallons a hour, Johnson 50. So
From the first equation
The Escobar family's sprinkler was was used for 14 hours and the Johnson's for 18 hours.
