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.
