"Columbia Corp.'s required ROI is 10%. Its East Division has operating assets of $7,500,000, profit margin of 15%, and asset turnover of 0.80. Calculate the East Division's operating income."

East Division operating income = $900,000

Explanation:

Profit margin = Net operating income/Sales    

Asset turnover = sales/average operating assets  

0.80= x/7,500,000    

x = 7500000*0.80    

= 6000000      

Thus, sales = 6,000,000    

Profit margin = net operating income/Sales    

15% = x /6,000,000    

x= 6,000,000*15%    

=900,000

Net operating income = 900,000

the investment was $14,174.196

explanation:

a lump sum means that the father of the example made one deposit and leave it be.

we need to know the value of a capital that generated at 4.05% per year during 28 years the sum of $48,613.24

now clearing the formula to solve for capital we got:

and we reach the answer investment = $14,174.20
