19) A factory sold a sofa to a furniture shop at a profit of 5%.The sopowner then sold the sofa to a customer at a profit of 25% for $5250. a)How much did the shopowner pay the factory for the sofa? The amount the shopowner paid the factory = (5250/125%) = $4200 b)What was the cost price of the sofa for the fatory? The cost price = 4200/(1+5%) = $4000 c)If the factory sold the sofa directly to the customer for $4500,find its profit per cent. Profit percentage = (4500 - 4000)/4000 * 100% = 12.5% 2010-11-21 20:46:35 補充: 15)Overall profit percent = (250 + 35*1.6 - 220 - 35)/(220+35) * 100% = 20%

其他解答:

{(5250/125%)-[4200/(1+5%)]}/4000*100%63D0B758E2D502CC
