Aclothing store put a sales price of $57 on a purse. before the markup, the store paid $30 for the purse. what percent markup did the store put on the purse?

Gross Profit Margin = Sales Price – Unit Cost = $57 – $30 = $27.

Markup Percentage = Gross Profit Margin/Unit Cost = $27/$30= 90%.

90% markup

Sales Price = Cost X Markup Percentage + Cost = $30 X 90% + $30= $57

is there supposed to be a diagram or a graph for this one? ?
