first, your sentence "每0.25单位成品卖1.5元" shoud be changed by 每0.25"KG"成品卖1.5元..... then ... we can know 1.5元/0.25kg = 6元/kg
because of 商人的卖价比买价高50%,
so we got (1.5 * Pa + 6 * Pb) * (1 + 50%) = 6 * (1.5 +6 )
and because of A与B果仁所花的总成本一样,
so we can get 1.5 * Pa =6* Pb
then .... you can get Pa , right ? ^-^作者: olympicdai 时间: 2002-11-25 15:05
