解：（1）根據(jù)題意，可得y＝100025x，化簡(jiǎn)得y＝40x；（2）根據(jù)題設(shè)可知自變量x的取值范圍為0＜x＜85.方法總結(jié)：反比例函數(shù)的自變量取值范圍是全體非零實(shí)數(shù)，但在解決實(shí)際問題的過程中，自變量的取值范圍要根據(jù)實(shí)際情況來確定.解題過程中應(yīng)該注意對(duì)題意的正確理解.三、板書設(shè)計(jì)反比例函數(shù)概念：一般地，如果兩個(gè)變量x，y之間 的對(duì)應(yīng)關(guān)系可以表示成y＝kx（k 為常數(shù)，k≠0）的形式，那么稱y 是x的反比例函數(shù)，反比例函數(shù) 的自變量x不能為0確定表達(dá)式：待定系數(shù)法建立反比例函數(shù)的模型結(jié)合實(shí)例引導(dǎo)學(xué)生了解所討論的函數(shù)的表達(dá)形式，形成反比例函數(shù)概念的具體形象，從感性認(rèn)識(shí)到理性認(rèn)識(shí)的轉(zhuǎn)化過程，發(fā)展學(xué)生的思維.利用多媒體創(chuàng)設(shè)大量生活情境，讓學(xué)生體驗(yàn)數(shù)學(xué)來源于生活實(shí)際，并為生活實(shí)際服務(wù)，讓學(xué)生感受數(shù)學(xué)有用，從而培養(yǎng)學(xué)生學(xué)習(xí)數(shù)學(xué)的興趣.
