一、用不等式表示不等关系例1某商店先从广州以每件15元的价格购进某种商品10件,后来又到深圳以每件12.5元的价格购进同一种商品40件,如果商店销售这些商品时,每件定价x元,获得大于12%的利润,用不等式表示上述问题中的不等关系,并检验x=14(元)是否使不等式成立?分析商品的销售利润=(销售价格-成本价格)/(成本价格)× First, the inequalities that ranged from Example 1 a shop first from Guangzhou to 15 yuan for each purchase of a product of 10, and later went to Shenzhen to buy a piece of the same price of 12.5 yuan 40, if When the store sells these items, each item is priced at x $ and gets a profit of more than 12%. Inequality is used to express the unequal relationship among the above problems and test whether x = 14 (yuan) holds the inequality. Analysis of the sales profit of the product = ( Sales Price - Cost Price) / (Cost Price) ×
