Answer:
Required Sale is $410,000
Step-by-step explanation:
First we have to determine the target profit.
Desired Profit = $100,000 + $40,000 = $140,000
As we know that the selling price is the sum of variable cost and contribution margin, so,
Sales = Variable cost ratio + Contribution margin ratio
100$ = 30% = Contribution margin ratio
Contribution margin ratio = 100% - 30% = 70%
Formula for target sales is as follow
Target Sales = ( Fixed cost + Target profit ) / Contribution margin ratio
Target Sales = ( $147,000 + $140,000 ) / 70% = $410,000
