    Sandy now has 280 stickers because it’s a ratio of 1:4 and if you add 1 and 4 you get 5. 1000%5=200 but Sandy gave Ken 80 so 200+80=280 and that’s the answer.

    The ratio is 1:4 and 1+4=5. 1000%5=200. Sandy gave Ken 80 so 200+80=280. So 280 is the answer.

    Sandy had 280 stickers in the beginning. I know this because the question says, that S+K=1000 and after Sandy had given Ken 80, Ken had 4x as many as Sandy. Which means that S+K=5S. Using this, S would equal 200 where as K would equal 800. BUT, the question asks what the answer was BEFORE Sandy gave Ken 80 stickers so, to get to the answer, Ken has to give Sandy 80 which leaves us with the answer 280 stickers.

    First, you divide 1,000 by 4 which is 250. 1,000-250 is 750. 750-80 is 670 which is Ken’s number. After that, you take away 670 from 1,000 and get left with 330.

    Sandy had 330 stickers at the start.

    Oh no! I need to do that again!

    First, you divide 1,000 by 5 which is 200. 1,000-200 is 800. 800-80 is 720 which is Ken’s number. After that, you take away 720 from 1,000 and get left with 280.

    Sandy had 280, not 330, stickers at the start.
