    Answer: 67

    Step-by-step explanation:

    Let x = number of passengers.

    Case M: x< = 75 (no refund)

    Cost per passenger = $230

    To generate the revenue, we should satisfy

    230x = 15990

    x = 69.5

    Set x = 67 in order to generate the revenue.

    Case N: x>75

    Cost per passenger minus refund = 230 - 5 = $225

    Therefore

    225x = 15990

    x = 71.1

    Because x<75, ignore this answer.

    More than 75 passengers will generate more than $15990.
