Answer:
$1 per unit
Explanation:
fixed costs $470
labor costs $20 per worker
first worker
produces 20 units,
total cost $490 / 20 units = $24.50 per unit
variable cost = $20 / 20 units = $1 per unit
second worker
produces 15 units
total cost $510 / 35 units = $14.57 per unit
variable cost = $40 / 35 units = $1.14 per unit
third worker
produces 10 units
total cost $530 / 45 units = $11.78 per unit
variable cost = $60 / 45 units = $1.33 per unit
fourth worker
produces 5 units
total cost $550 / 50 units = $11 per unit
variable cost = $80 / 50 units = $1.60 per unit
