The kindergarten originally planned to buy 36 sets of children's clothing at 45 yuan each, but because the stock was out of stock, it changed to 54 yuan for each set of children's clothing. How many sets can it buy? (What can be found further?)
幼儿园原计划买每套45元的儿童服装36套，由于断货，改买每套54元的儿童服装，可以买多少套？(进一步可以求出什么？)
