PROFIT AND LOSS When a merchant purchases an item, he adds a percent of this cost to what he paid to arrive at a selling price. This amount is called his profit. Example: A radio sells for $40, giving the dealer a 25% profit. What was his cost? Solution: If the dealer gets back all of his cost plus an extra 25%, then the $40 sales price represents 125% of his cost. 1.25x = 40 125x = 4000 x = $32 Example: Joan’s Boutique usually sells a handbag for $80, which yields a 33 % profit. During a special sale, 3 the profit is cut to 10%. What is the sale price of the handbag? Solution: $80 represents 133 % of the cost. 4 x = 80 3 1 1 3 4x =240 x = 60 If the cost was $60 and the dealer wishes to add 10% for profit, he must add 10% of $60 or $6, making the sale price $66.
