Question

The guy took 15 pieses and there is 4 left

Answer 1

The number of pieces in the bowl before she added the 20 is 8 pieces of candy

Here, we want to get the number of pieces in the bowl before the addition of the 20 pieces

Let the number of pieces before the addition be n

she added 20 pieces to what is there initially, this brings the total to;

`n\text{ + 20}`

Now, two days after the addition, half of the above is gone

Half of the above is;

`(n+20)/(2)`

Now, the difference between the number of pieces in the bowl after the addition of the 20 and the half gone is 14; we have the equation as thus;

`\begin{gathered} n\text{ + 20 - (}(n+20)/(2))\text{ = 14} \\ \\ 2(n+20)-(n+20)\text{ = 28} \\ n\text{ +20 = 28} \\ n\text{ = 28-20} \\ n\text{ = 8} \end{gathered}`
