A Desk! (-$90)

A desk would be really useful for studying! You don't know much about the topics you're going to be tested on, but you do know the importance of a good working space. You tell Darla as much, proud of your initiative, and she seems super proud of you herself.

"That's great to hear, Debbie!" Darla says, taking the money from you and punching some keys on her computer. "You're such a smart girl. You're really headed for big things."

....Okay, well, she doesn't say that, but you don't understand what she does say, which gives you every right to make believe! Desk acquired.
