Answer:
the  labor efficiency variance is $35,244 favorable 
Explanation:
The computation of the labor efficiency variance is shown below:
As we know that 
Efficiency Variance is 
 = Standard rate × (Standard hours - Actual Hours)
= $13.20 × (9.4 ×1,050 units - 7,200 hours)
= $13.20 × (9,870 hours - 7,200 hours)
= $35,244 favorable 
hence, the  labor efficiency variance is $35,244 favorable 
 
        
             
        
        
        
Answer:
Desing A is a better deal as the equivalent annual cost is lower than desing B
Anywa, bot desing cost are above the city collections thus, it cannot afford the sanitary systems unless it raises taxes 
Explanation:
<em><u>Desing A </u></em>
F0 405,000 
operating and maintenance cost 51,000 for 14 years
Present value of the operating and maintenance cost:
 
 
C	= $ 51,000.00
time =	14 years
rate	= 0.07
 
 
PV	$446,018.8673 
net worth: $ 851,081.87
equivalent annual cost:
 
 
PV	851,082
time	14
rate	0.07
 
 
C  $ 97,316.904 
<u><em>Desing B</em></u>
F0 251,000
operating and maintenance cost 89,000 for 14 years
 
 
C	89,000.00
time	14
rate	0.07
 
 
PV	$778,346.6507 
net worth: $ 1,029,346.65
equivalent annual cost:
 
 
C  $ 117,700.580
