Answer: The internal auditor discovered it when performing a routine audit of expense reimbursements

Answer: c. 78,000 equivalent units.
Explanation:
Equivalent units for conversion is calculated as:
= Units completed and transferred out + Equivalent ending work in process
Units completed and transferred out:
= Units started into production - Ending units 
= 90,000 - 20,000
= 70,000 units 
Equivalent ending work in process = 40% * 20,000 work in process units 
= 8,000 units 
Equivalent units for conversion = 70,000 + 8,000
= 78,000 units 
 
        
             
        
        
        
Return on  Investment = 83% or 0.83
total Profit = 75000
term = 6 yrs
annual profit = 75000 / 6 = 12500
initial investment = 15000
ROI = Net  Profit / Total Asset
       = 12500 / 15000
       = 0.83  or  83% (0.83 x 100%)
        
             
        
        
        
Answer:
Expected return on equity is 11.33%
Explanation:
Using Weighted Average Cost Capital without tax formula, overall rate of return is given by the formula:
WACC=(Ke*E/V)+(Kd*D/V)
Kd is the cost of debt at 6%
Ke is the cost of equity at 12%
D/E=1/2 which means debt is 1 and equity is 2
D/V=debt/debt+equity=1/1+2=1/3
E/V=equity/debt+equity=2/1+2=2/3
WACC=(12%*2/3)+(6%*1/3)
WACC=10%
If the firm reduces debt-equity ratio to 1/3,1 is for debt 3 is for equity
D/V=debt/debt+equity=1/1+3=1/4
E/V=equity/debt+equity=3/1+3=3/4
WACC=10%
10%=(Ke*3/4)+(6%*1/4)
10%=(Ke*3/4)+1.5%
10%-1.5%=Ke*3/4
8.5%=Ke*3/4
8.5%=3Ke/4
8.5%*4=3 Ke
34%=3 Ke
Ke=34%/3
Ke=11.33%
