Answer:
the second day ticket
Step-by-step explanation:
We would purchase the ticket with the highest net benefit
Net benefit = Benefit - cost of ticket
First day
Net benefit = $120 - $115 = $5
Second day
Net benefit = ($120 + $50) - $150 = $20
Third day
Net benefit = ($170 + $15) - $170 = $15
The second day yields the highest net benefit
