Answer:
3.2 & 16%
Step-by-step explanation:
Degree of operating leverage = Contribution margin / Pretax net income
Degree of operating leverage = $80,960 / $25,300
Degree of operating leverage = 3.2
Degree of operating leverage 3.2 means if sales (or contribution margin) increases by 1%, income increases by 3.2 %.
Thus, Expected % change in income = Increase in sales * degree of operating leverage
Expected % change in income = 5% * 3.2
Expected % change in income = 0.5 * 3.2
Expected % change in income = 0.16
Expected % change in income = 16%
