Mark up and discounts are not the same numbers. Not sure what the regular price is or the sale price, but let's say the regular price was $10 a yard. 60% off would mean the sale price is $4 a yard. If that is their cost, then they marked it up 150%. (The cost plus 1.5 times as much) If they had marked it up 60%, the regular price would have been $6.40.
