I might be mistaken but I think this is just a matter of comparing the original cost and passenger amounts to the new cost and passenger amounts.
Original amounts being:
$460 and 980
New amounts being:
$460 + $36 and 980 + 8
To compare the prices find the cost per passenger both times and take the orginal away from the new.

Is this what we are supposed to do?Does .04 become the rate of change?
