Question 1115252: Hello! I'm a little stumped on this problem! I would appreciate any help. I'm just a little confused. When it means forfeit, am I paying 25 percent more for the ticket or is the price being reduced?
In planning a trip to New Zealand six months in advance, you find that an airline offers two options: Plan A: You can buy a fully refundable ticket for $2200. Plan B: You can buy a $1200 ticket but you forfeit 25% of the price if the ticket is changed or canceled.
a) What are all possible ticket costs (What you pay for each plan if you keep the ticket or need to change/cancel the ticket)
b) How would you decide which ticket to buy?
Thank you so much! This really helps me!
