Answer:
The best price is $50 per person which results in maximum profit.
Step-by-step explanation:
Helicopter company has capacity for 8 people in one trip including the pilot and it costs them $5 per person therefore the price cannot be lower than $35 (7 * $5). The marginal cost per trip is $35 therefore the company cannot charge the price below this. If the company chooses to charge one price for all, it should charge $50 per person as this will result in maximum profit.
