Answer
(a) 1400
(b) 21000
(c) 1400
(d) 21000
Work Step by Step
a. Profit = (Price per unit - variable expense per unit) * sales unit - fixed cost
=> $0 = (15 - 12) * Sales Unit - 4200$
=> Sales unit = 1400
b. Profit = ((Price per unit - variable expense per unit)/ Price per unit)* sales values - fixed cost
=> $0=\frac{(15-12)}{15} \times Sales Value - 4200$
=> Sales Values = $\frac{4200}{0.2}=21000$
c. Break-even sales unit = Fixed cost / (Price per unit - Variable cost per unit)
$= \frac{4200}{15-12}=1400$
d. Break-even sales unit = Fixed cost / (Price per unit - Variable cost per unit) / Price per unit
$= \frac{4200}{\frac{15-12}{15}}=21000$
