Answer:

They came back home at 12 pm

Explanation:

Giving the following information:

The Burkes pay their babysitter​ $5 per hour before 11 P.M. and​ $7.50 after 11 P.M. One evening they went out for 4 hr and paid the sitter ​$27.50.

We need to formulate the total cost:

TC= 5*x + 7.5*y

x=5*4= 20

y=7.5*1= 7.5

TC= 5*4 + 7.5*1= $27.5

They came back home at 12 pm
