Step 2 · Fresh numbers, every attempt

A shop buys a jacket for R480 and sells it for R720. What is the markup on cost?
50.0%✓ Correct

Step 3 · Optional add-on: a tutor when you need one

I keep getting the margin wrong on question 4.
TutorLet us look at your working. You divided by cost. For margin, divide the profit by the selling price.
Oh. So R240 ÷ R720 = 33.3%. Got it!
