在数学中,有两个利润计算公式:(1)总利润=总售价-总进价;(2)总利润=一件商品的利润×销售量.这两个求利润的公式是否完全一样,是否都能解同一道题?看下面一例:题目(北师大版《数学》八(下))某大型超市从生产基地购进一批水果,运输过程中质量损失5%,假设不计超市其他费用.(1)如果超市在进价的基础上提高5%作为售价,那么请你通过计算说明超市是否亏本;(2)如果超市至少要获得20%的利润,那么这种水果的售价最低应提高百分之几?(结果精确到0.1%)分析第(1)问超市是否亏本,只需算
In mathematics, there are two formulas for calculating profits: (1) Total profit = total selling price - total purchase price; (2) total profit = profit of one commodity x sales volume. Are these two formulas for profit exactly the same , Can solve the same problem? See the following example: The subject (Beijing Normal University “Mathematics” eight (below)) A large supermarket to buy a batch of fruit from the production base, the quality loss during transport 5%, assuming that excluding supermarkets Other costs (1) If the supermarket increases 5% on the basis of the purchase price as the selling price, then please calculate whether the supermarket is losing money or not; (2) If the supermarket has to obtain at least 20% profit, then the sales of this fruit (1) to ask whether the supermarket is losing money, just count
