Answer:
(a)
Mathematical Equation for break-even
F = QP - QV
Where
F = fixed cost
Q = Break-even quantity
P = Selling price
V = Variable cost
F = Q ( P - V )
Q = F / ( P - V )
Q = $319,800 / ( $650 - $450 )
Q = $319,800 / $200
Q = 1,599 units
(b)
Contribution Margin = Price per unit - Variable cost per unit
Contribution Margin = $650 - $450 = $200
Break-even Point in Units = Fixed Cost / Contribution margin per unit
Break-even Point in Units = $319,800 / $200 = 1,599 units
Step-by-step explanation:
Mathematical equation use the the break-even equation which represent the behavior of each element towards the break-even point.
Contribution per unit method use the contribution of each unit to calculate the break-even point.
