After model explanation: Given he removed 28 buttons from box B, he would have added 28 / 2 = 14 buttons to box A.
The final ratio of 4 :1 is the ratio based on the After model as follow (Box A + Box B) : Box B. As with all models, the goal is always to find what 1unit is worth, then the rest of the model can be solved no matter the question being asked.
