Respuesta :
If sandy has 8 and alex has 6 fewer than alex has 2. Since Jill has 2 then you add 8 plus 2 plus 2 which equals 12. So there is 12 all together
so alex would have 2 markers plus jills 2 markers plus 8 markers is 12 markers all together, feel free to comment if you don't understand fully, and i will try to better my explanation
