23、【問題】先閱讀下列文字，再解答下列問題：(8分)
初中數學課本中有這樣一段敘述：“要比較與的大小，可先求出與的差，再看這個差是正數、負數還是零。”由此可見，要判斷兩個代數式值的大小，只要考慮它們的差就可以了。
試問：甲乙兩人兩次同時在同一糧店購買糧食(假設兩次購買糧食的單價不相同)，甲每次購買糧食100千克，乙每次購糧用去100元。
(1)假設、分別表示兩次購糧的單價(單位：元/千克)。試用含、的代數式表示：甲兩次購買糧食共需付款元;乙兩次共購買千克的糧食;若甲兩次購糧的平均單價為每千克元，乙兩次購糧的平均單價為每千克元，則=;=。
(2)規定：誰兩次購糧的平均單價低，誰的購糧方式就更合算，請你判斷甲乙兩人的購糧方式哪一個更合算些?並說明理由。
