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
 
        
             
        
        
        
Answer:
1) The fixed overhead production-volume variance is $14400 favourable.
2) The fixed overhead spending variance is $9000 unfavourable. 
Explanation:
1)
Fixed overhead production volume variance 
= amount applied * amount budgeted
= 144000/30000 
= 4.80 per unit
= 4.80*33000 - 144000
= $14400 favourable
Therefore, The fixed overhead production-volume variance is $14400 favourable.
2)
fixed overhead spending variance 
= actual overhead - budgeted overhead 
= 153000 - 144000
= $9000 unfavourable
Therefore, The fixed overhead spending variance is $9000 unfavourable.
