Read the story, then answer.
The sticker boxMia and Ben sold stickers at the fair. Their box held three pages, four strips and six singles. A page holds one hundred stickers, a strip ten and a single just one. Zoe's class wanted one page, five strips and eight singles. Mia started with the singles, but she had six and eight were wanted. That was too few, so she opened a strip. Next came the strips: only three were left but five were wanted, so one page split into ten strips. Then she took the page. One page, eight strips and eight singles stayed in the box.
