Analysis: The red 144 yuan has more 26 yuan than the blue 1 18 yuan; 46 yuan of red pants is less than 58 of blue pants 12 yuan; The one who spends the most money buys the one with high price: all red clothes: 6* 144=864 yuan; 6*58=348 yuan * * Remove 864+348= 12 12 yuan. Spend the least and buy the lowest price: all-red clothes: 6* 1 18=708 yuan; 6*46=276 yuan * * * costs 984 yuan. I think it can be matched with red and blue, because the topic only asks about the highest and lowest money to buy a set, of course, the highest 12 12 yuan's lowest 984 yuan.
