To discuss: The relationship between external financing and growth rate.
Explanation of Solution
The relationship of external financing and growth rate is a primary element in the area of financial planning.
- The firm maintains 100% capacity utilization to make the things easy and simple.
- When growth rate is at 15% the EFN is negative, this shows the company has more funds.
- When growth rate at 20% and 25% the EFN is positive, this indicates the company needs additional financing for the upcoming period.

To determine: The rate at which EFN is zero.
Explanation of Solution
The rate at which external financing needed is zero at 15% growth rate. As the difference of total assets and total liabilities of external financing needed at the rate of 15% growth rate is -$12,785 this shows that EFN is zero since it exceeds the liabilities.

To discuss: Reason for the difference of internal growth using graphical method and equation method.
Explanation of Solution
The (ROA x b) is the element which is used throughout the text. This is based on the ROA using ending balance sheet numbers of assets and beginning balance sheet number of assets whereas the internal growth rate and ROA calculated by the equations on a abbreviated form is based on the assets which will not exists once the net income earned.
Thus, the rate 15% at which the company external financing needed is negative.
