Luis and his best friend Faith want to spend as much time as possible at the local amusement park this summer, so they’re going to buy season passes. The passes are normally $120 each, but for three days only, they’re on sale: Buy one, get one half off. Luis agrees to wait in line to buy them the season passes, and they’ll split the cost evenly. How much will Faith owe Luis?

The normal price for one season pass is $120, but they are currently on sale with a "Buy one, get one half off" offer.

  1. The price of the first season pass is $120.

  2. The price of the second season pass, with the half-off deal, is half of $120: \[ \text{Price of second pass} = \frac{120}{2} = 60 \]

  3. Now, add the prices of both season passes to find the total cost: \[ \text{Total cost} = 120 + 60 = 180 \]

  4. Since Luis and Faith are splitting the cost evenly, we divide the total cost by 2: \[ \text{Cost per person} = \frac{180}{2} = 90 \]

Thus, Faith owes Luis $90.
