Answer:
the mark up used by the retailer is 115.12% of the wholesale price
Step-by-step explanation:
Mark-up is the percentage increase of the retail price over the wholesale price
Mark-up = (difference between retail and whole sale price / retail price ) x 100
difference between retail and whole sale price = $9.25 - $4.30 = $4.95
(4.95 / 4.3) x 100 = 115.12%.
