Question 1074840: Monica flew home from vacation with a heavy bag. With the first airline she flew, Monica had to pay $17 to check her bag, plus $17 for every kilogram that her bag was over the weight limit. The next flight was with another airline that had the same weight limit. Monica had to pay $19 per kilogram that her bag was over the weight limit, in addition to the checked bag fee of $15. By coincidence, the fees ended up being the same with both airlines. How far over the weight limit was the bag? How large was each airline's fee?

You can put this solution on YOUR website! Monica flew home from vacation with a heavy bag.
With the first airline she flew, Monica had to pay $17 to check her bag, plus $17 for every kilogram that her bag was over the weight limit.
The next flight was with another airline that had the same weight limit.
Monica had to pay $19 per kilogram that her bag was over the weight limit, in addition to the checked bag fee of $15.
By coincidence, the fees ended up being the same with both airlines.
How far over the weight limit was the bag?
How large was each airline's fee?
:
let x = the amt over the weight limit
17x + 17 = 19x + 15
17 - 15 = 19x - 17x
2 = 2x
x = 1 kg over the limit
"How large was each airline's fee?"
17(1) + 17 = $34
19(1) + 15 = $34
