hakim flew home from vacation with a heavy bag. with the first airline he flew, hakim had to pay $28 to check his bag, plus $7 for every pound that his bag was over the weight limit. the next flight was with another airline that had the same weight limit. hakim had to pay $9 per pound that his bag was over the weight limit, in addition to the checked bag fee of $14. by coincidence, the fees ended up being the same with both airlines. how large was each airline's fee? how far over the weight limit was the bag?
