Answer:
Mark-up= 30%
Step-by-step explanation:
Mark-up is profit expressed as a percentage of the total production cost.
Full cost per unit = (Variable cost + Fixed cost)/No of units
Full cost per unit = (1,156,000 + 104,000)/9000= 140 per unit
Profit per unit = Net income / No of units
=378,000/9,000
= $42 per unit
Mark-up = profit per unit/cost per unit
= 42/140 × 100
= 30%
