What? Maybe I'm missing some glaring issue, but this one doesn't even seem like a puzzle to me...

..................A.........B
At hire:....$500....$500
6 mos:....$500....$525
1 year:....$600....$550
1.5 yr:....$600....$575
2 year:....$700....$600

...There are no percentages to contend with, B is just getting less money.
