Answer:
 the efficiency variance for variable overhead setup costs is $4,810 favorable 
Explanation:
The computation of the efficiency variance for variable overhead setup costs is shown below;
= ((15,700 ÷ 265) × 4.25) × $45 - ((15,700 ÷ 325) × 3) × $45
= $11,330.6604 - $6,521.5384
= $4,809.12 favorable 
= $4,810 favorable
hence, the efficiency variance for variable overhead setup costs is $4,810 favorable 
 
        
             
        
        
        
A rock-climbing school faces two demand curves. The demand by local residents is Q = four hundred - zero.fivep and the demand by others is Q = five hundred - zero.fivep. The marginal costs of serving either local residents or other are constant at one hundred dollars. If the rock-climbing school system third-degree price discrimination, It will charge local citizens and others a price of four hundred fifty dollars and five hundred fifty dollars, respectively.
        
             
        
        
        
Answer:
25 Days
Explanation:
Average Account receivables: 
= (Accounts receivables, beginning of year + Account receivables, end of year) ÷ 2
= (45,000 + 35,000) ÷ 2 
= 40,000
Account Receivables Turnover = Net Sales on Account ÷ Average Account Receivables  
Account Receivables Turnover = 584,000 ÷ 40,000 
                                                     = 14.6 times
No. of Days Sales in Accounts Receivables: 
= No. of Days in a year ÷ Account Receivables Turnover
= 365 ÷ 14.6 
= 25 Days
