最佳解答:
A computer game is marked at $320, and it is sold at a discount of 30% It the discount is 48% of the cost price, find the profit per cent The discount is 320x30% = $96 The sold price = 320 – 96 = $224 The cost price = 96 / 48% = $200 The profit percent = (224-200)/200 = 12%
其他解答:
The sold price $320x(1-30%) =$320x70% =$224 The cost price $320x(1-48%) =$320x52% =$166.4 The profit is 224-166.4/166.4x100% =57.6/166.4x100% =0.346153846x100% =34.6153846% =34.62% (cor. to 2 sig.fig.) 2006-11-23 22:43:58 補充： 樓上錯了樓下answer錯了 ha~ha~|||||The sold price = $320 * (1-30%) = $224 The cost price = $320 * (1 -48%) = $166.4 The profit =$224-$166.4/$166.4 * 100% = 34.6% (to 3.sig.fig) 2006-11-23 16:44:42 補充： 樓下的 你括號內的應該是d.p 啊
