Suppose the values for this problem change to:

Total Assets: $2,346,845

Sales Growth: 35.8%

Profit Margin: 6.8%

At what growth rate would long-term debt stay the same, i.e. no new debt is needed? Using Excel's goal seek is the easiest way to solve this. You can also try to solve the equation arithmetically. Round your percentage to one decimal, i.e. you would enter 12.34% as 12.3..
