Answer:
(A) $700,000
(B) 12,308 units
Explanation:
(A) The before-tax profit that is needed to achieve an after-tax target of $420,000 can be calculated as follows
= after-tax income/1-tax rate
= $420,000/(1-40/100)
= $420,000/1-0.4
= $420,000/0.6
= $700,000
(B) The number of units that will yield operating income can be calculated as follows
= desired contribution margin/Contribution margin per unit
Desired contribution margin= $445,000 + $295,000 + $700,000
= $1,440,000
Contribution margin per unit= 300-(90+66+15+12)
= 300-183
= 117
Therefore the number of units that will yield the operating income is
= 1,440,000/117
= 12,308 units
