Answer:
a. Personal Service System = 1.25 and Automated Self-Service System = 2.50
b. Automated Self-Service System will produce the higher net income.
Step-by-step explanation:
1. Degree of Operating Leverage (DOL)
Degree of Operating Leverage (DOL) shows the times Earnings Before Interest and Tax (EBIT) will change as a result of a change in sales contribution.
Degree of Operating Leverage (DOL) = Contribution ÷ Earnings Before Interest and Tax
Therefore,
Degree of Operating Leverage (DOL) for each service will be as follows :
Personal Service System = $570,000 ÷ $456,000
= 1.25
Automated Self-Service System = $1,140,000 ÷ $456,000
= 2.50
2. Effect on Net Income
If Sales increase by $228,000, that is a 10 % increase.
Which will have the following effect on Net Incomes of the proposed services :
Personal Service System = 10 % × 1.25 = 12.5 %
Automated Self-Service System = 10 % × 2.50 = 25 %
Conclusion
Automated Self-Service System will produce the higher net income.
