Return on Investment is the proportion investment that is earned as operating income.
Operating income = ROI × investment = 20%× 540,000=108,000
Profit per unit = total operating income /Number of units
=$108,000/11,500 units
=$9.391 per unit
Mark-up = (Profit per unit ÷unit cost)× 100
Mark- up = $9.391 /35 × 100 =26.83
Mark-up = 26.83%
