Question

Wenxuan, Charlene and Siti shared a box of stickers. Wenxuan took 8 more than of the total number of stickers. Charlene took 7 more than of the remaining 1 1 3 2 stickers. Siti took the last 23 stickers. How many stickers were there in the box at first?​

Answer 1

We can start solving the problem by using algebraic equations. Let x be the total number of stickers in the box at first.

According to the problem, Wenxuan took 8 more than of the total number of stickers, so he took x + 8 stickers.

The remaining stickers after Wenxuan took his share is x - (x+8) = x - x - 8 = -8 stickers.

Charlene took 7 more than of the remaining stickers, which is -8 + 7 = -1 stickers.

So, Charlene took x - (x+8) + 7 = -1 stickers.

Siti took the last 23 stickers, so the total number of stickers remaining is -1 - 23 = -24.

Now we can use this information to set up the equation:

x + (x+8) + (x-x-8+7) + (-1-23) = x

Solving for x we get x = 32

Therefore, there were 32 stickers in the box at first.
