Let x = original price
Let x - 55 = amount the mat was reduced to
Let x - .25x = amount the mat was reduced to
x - 55 = x - .25x
Solve for x.
Let 89 = cost of jacket
Let 111.25 = selling price
Let 111.25 - 89 = 22.25 = the amount of markup
Let % = per cent of markup.
Let 141.60 = cost of boots plus duty
Let 21.60 = duty
Let 141.60 - 21.60= 120 = cost of boots alone
Let % = per cent duty charged on the boots.
Let 2650 = Kim's salary
