Answer:
33 markers
Explanation:
lets give them symbols first:
x=markers
4x because there are 4 boxes for markers and we don't know if there is any markers so we say X for it.
Next, we do know how many markers, there are 8 markers, so we replace the x with 8
4(8) this means we have to multiply so 4 times 8 is 32.
Then it says he adds 1 marker in each of the boxes.
remember that there are 4 boxes.
4(1) is 4 times 1 which is 4
So, simply do 32+4= 36
