Answer:
A) decrease the degree of operating leverage
Explanation:
The contribution margin is
sales - variable:
(sales + 2) - (variable + 2) = sales - variable
no change
so B is FALSE
as the contribution margin ratio is:
(sales - variable ) / sales
this increase will impact the contribution margin ratio.
(sales + 2 - (variable +2))/ (sales + 2)
(sales - variable) / (sales + 2)
the CMR will decrease.
so D is FALSE
the break-even on sales will increase as the CMR decreases
more units are needed to fullfil the fixed cost
so C is FALSE
A) decrease the degree of operating leverage
ΔEBIT / Δrevenue
sales increase and the variable cost increases
a change in the sales revenue will not be as efficient as it was before the degree of leverage will decrease.
