一些有难度的数学问题中,有的条件除告诉我们一层意思外,还含有另一层意思。弄清另一层含义,往往能成为解题的突破口。为民商店购进一批球鞋,每双的售出价比购进价多16%。如果全部卖出,可获利960元,在卖出80双时,还差240元才够成本。每双球鞋的售出价是多少元?
Some difficult mathematical problems, some of the conditions in addition to tell us a meaning, but also contains another layer of meaning. To understand the meaning of another layer, often can become a breakthrough problem solving. Buy a number of civilian shops shoes, each pair of sales price more than the purchase price of 16%. If all sold, profit 960 yuan, sold 80 pairs, the difference is only 240 yuan enough to cost. What is the selling price of each pair of shoes?
