: Могло. Решение. Пусть начальная цена была 1 р. 10 коп. Тогда на распродаже ложка стоила 10 коп., а вилка — 11 коп. Замечание. Пусть x — начальная цена в копейках. Тогда x должно быть больше 100 (поскольку цена ложки на распродаже должна быть положительной), делиться на 10 (поскольку цена вилки на распродаже должна выражаться целым положительным числом копеек) и удовлетворять неравенству x–100 < x/10 ⇔ x < 111 1/9. Таким образом, x = 110 — единственная цена, удовлетворяющая всем перечисленным условиям
My room is small, but very cozy. I am very happy and comfortable here, as have all that I need. Room square shape, very bright, because a large window facing south.Before the window is a table with a lace table lamp beside her - stand for pens and pencils. The desk drawers I keep notebooks and other school stuff. At the table - the chair on which I sit, when I do homework.Near the right wall next to the desk - a bookshelf with my favorite books and textbooks. Next - wardrobe.On the other side of the window located my sports area - the Swedish wall, beam, which can be tightened in order to train the hand and skin Boxing "pear". Here I am doing morning exercises.At the same wall is a my bed, or rather spread out sofa. When friends come to me, it can make, so it was convenient to sit. On the wall above the sofa hangs a small carpet. Bed linen is stored in the chest that stands in the corner. On my dresser sitting soft fluffy friends: bear, rabbit and dog with one ear. On the wall above the chest of drawers - some of my drawings.On the floor lay a carpet of gray-green color. Wallpaper on the walls of the room are light green, light-wood furniture.
