Jada flew home from vacation with a heavy bag. With the first airline she flew, jada had to pay $29 to check her bag, plus $4 for every pound that her bag was over the weight limit. The next flight was with another airline that had the same weight limit. Jada had to pay $11 per pound that her bag was over the weight limit, in addition to the checked bad fee of $15. By coincidence, the fees ended up being the same with both airlines. How far over weight limit was the bag? How large was each airlines fee?
