Answer:
When target profit is $4150 sales unit is 550
When target profit is $8800 sales unit is 607
Step-by-step explanation
Unit sales to attain a target profit =fixed expenses +target profit/contribution per unit
Fixed expenses is $40,400
target profit of $4150
contribution per unit =selling price - variable cost
selling price is $135
variable cost is $54
contribution per unit=$135-$54
=$81
Unit sales at target profit of $4150=($40,400+$4150)/$81
=550 units
Unit sales at target profit of $8,800=($40,400+$8,800)/$81
=607 units
