你能根据所学知识找到计算上面算式的简便方法吗?请你利用你找到的简便方法计算下式：……

22、某校为实施国家“营养早餐”工程，食堂用甲、乙两种原料配制成某种营养食品，已知这两种原料的维生素C含量及购买这两种原料的价格如下表：

甲种原料乙种原料

维生素C(单位/千克)600400

原料价格(元/千克)95

现要配制这种营养食品20千克，要求每千克至少含有480单位的维生素C.设购买甲种原料x千克.

(1)至少需要购买甲种原料多少千克?

(2)设食堂用于购买这两种原料的总费用为y元，求y与x的函数关系式，并说明购买甲种原料多少千克时，总费用最少?(8分)

23、【问题】先阅读下列文字，再解答下列问题：(8分)

初中数学课本中有这样一段叙述：“要比较与的大小，可先求出与的差，再看这个差是正数、负数还是零。”由此可见，要判断两个代数式值的大小，只要考虑它们的差就可以了。

试问：甲乙两人两次同时在同一粮店购买粮食(假设两次购买粮食的单价不相同)，甲每次购买粮食100千克，乙每次购粮用去100元。

(1)假设、分别表示两次购粮的单价(单位：元/千克)。试用含、的代数式表示：甲两次购买粮食共需付款元;乙两次共购买千克的粮食;若甲两次购粮的平均单价为每千克元，乙两次购粮的平均单价为每千克元，则=;=。

(2)规定：谁两次购粮的平均单价低，谁的购粮方式就更合算，请你判断甲乙两人的购粮方式哪一个更合算些?并说明理由。
