Which situation could best be represented by this linear equation?

24x + 38y = 520

The term "which" has me thinking this is a multiple choice question but we were not given those so I can just make one up that can be represented by this equation.

KtreyB has been looking to invest his money into two different companies and today is the day he decided to pull the trigger. The first company he invested in sold their stocks at $24 per share. He decided to buy x amount of shares. The second company has a little more promise so their stocks were $38 a share. He bought y amount of shares here, what a steal. The total money invested into both companies ended up being $520, not too bad for a day on the market. Cheers to hopes of exponential growth!

the answer to the question is punishment. or more specifically, positive punishment.

positive punishment occurs when a behavior is given a negative consequence for the individual doing the behavior.

sara no longer wants to ask questions (the behavior) because she is ridiculed by mr. smith (the punishment).

reinforcement is inaccurate because reinforcement always gives positive consequences for the individual doing the behavior, be it by introducing a pleasant consequence or removing an unpleasant one.
