Answer and Explanation:
The computation is shown below:
a)
Fixed manufacturing overhead per unit  is 
= $29,350 ÷ 9,940 
= $2.95 per unit
Now  
Variable cos per calculator is 
= $10.70- $2.95 
=$ 7.75 per calculator
b)Variable costing income will be lower by 
= 750 units × $2.95
= $2,213
= Fixed cost + n × variable cost per calculator
c) The Cost formula (y) is  
= $29,350 + 7.75 x
 
        
             
        
        
        
Answer:
loanable amount after Fed operation = $950 M
Securities after fed operation = $50 M 
attached below is the T-account table 
Explanation:
Given data:
For assets : securities = $100 M ,  Loans = $800 M 
For Liabilities :  Constant demand deposit = $1000 M
difference between the assets and liability = $100 M  and this makes the Banking system unbalanced hence the Banking system needs the intervention of the Fed. and the reduction in the required reserve ratio from 10% to 5% is the right action 
How with the reserve ratio reduced to: 0.05 
hence required  Minimum required securities after operation = 0.05 * 1000 M = 50 M
Note : Total demand deposits = securities + loanable amount
therefore loanable amount after Fed operation = $1000 M - $50 M = $950
Attached below is the T-table 
When both tables are compared it can be seen that there is a significant increase  in the loanable amount after the Fed's operations and increase in Loanable amount transcends to increase in Monetary base
 
        
             
        
        
        
Answer:
Explanation: from the question above, disbursement for the period is check for $4,200.
Collection for the period is a check for $6,800.
Net float is $35,900 + $6,800 - $4,200. = $38,500
