Answer:
Income will increase by $84.
Explanation:
The break-even point is the number of units required to cover the fixed costs. Net income is zero.
First, we need to calculate the unitary variable cost:
Unitary variable cost= 120*0.3= $36
Now, the unitary contribution margin:
unitary contribution margin= 120 - 36
unitary contribution margin= $84
Income will increase by $84.
