某商场销售一种“艾丽莎”品牌服装，销售经理根据销售记录发现，该服装在过去的一个月内（以30天计）每件的销售价格P（x）（百元）与时间x（天）的函数关系近似满足P（x）=1+$\frac{k}{x}$（k为正的常数），日销售量Q（x）（件）与时间x（天）的部分数据如表所示：

已知第2哦天的日销售量为126百元．

（Ⅰ）求k的值；

（Ⅱ）给出以下三种函数模型：

①Q（x）=a•b^x；

②Q（x）=a•log_bx；

③Q（x）=a|x﹣25|+b．

请您根据如表中的数据，从中选择你认为最合适的一种函数来描述日销售量Q（x）（件）与时间x（天）的变化关系，并求出该函数的解析式；

（Ⅲ）求该服装的日销收入f（x）（1≤x≤30，x∈N^*）（百元）的最小值．

   A couple of years ago, I went to a lady's house to buy some medicine. Upon entering the house, I1that there was a piano in the living room beside the wall.Being a piano music lover and player, I asked if the woman played. She said “Yes” and2that she had been taking lessons—at the age of 54!
   “I have been3for 8 years now.” I said, after hearing her words.“Then you must play a song for me before you leave,” she requested(请求).
   I thought she was kidding and I4smiled. When I had bought the medicine, she asked me to play some music. I thought for a moment and 5to play David Lanz’s Return to the Heart,6she had so much passion(热情)for and interest in music, and it’s one of my favourite songs.
   I played the song to the best of my ability(能力), putting as much emotion into it as possible. She7it. As I was about to step out of the door, I heard a weak voice calling, “Young man!”I8, and saw an old lady taking one little step at a time with the help of another woman. “I wanted to come out to thank you for the9song that you played. I have been very sick, and it's very hard for me to get out of bed, but I really wanted to thank you for the song. It made me feel good.” she said. With that, she turned around and walked slowly back to her room.
   I was deeply touched by her10and felt a deeper understanding for the song. It was11to its name, returning to one’s heart to12and joy.
