(a) Cost of a bag of GG rice = $54/ (1+80%) = 54/1.8 = $30 (b) Let x be the cost of Thai rice per kg. (0.6*5 + 0.4x)*5 = 30 3 + 0.4x = 6 0.4x = 3 x = 7.5 Cost of Thai rice per kg is $7.5

其他解答:

都好耐冇做，都有d難難地感覺。 a. the cost of a bag of a cg rice is: $ 54/(1+0.8) 個profit道理係賺多左0.8包所以54蚊值1.8包 =$30 b. the cost of thai rice per kg $ 40%係thai rice 唔等於就係$30既40% 因為唔一定會係1公斤 let the cost be x$, (x*0.4+5*0.6)*5=30 x*0.4+3=6 x*0.4=3 x=3/0.4=7.5 泰米緊係貴d架la 2007-11-18 20:47:24 補充： 我地同時答岩，大家都答得好準﹗揀佢la ，因為佢答得快而準。
