### Subject: Psychology

Sarah gets a speeding ticket, and her parents take her car away for 2 weeks. This is an example of what type of operant consequence? (i.e. positive/negative reinforcement or positive/negative punishment)

This would be an example of negative punishment. Negative punishment occurs when, after a voluntary behavior, a desirable stimulus is taken away/removed in order to decrease the behavior. In this scenario, Sarah's parents take away her car (the desirable stimulus) in order to decrease the behavior (speeding). Remember: - Negative = REMOVE/TAKE AWAY a stimulus - Positive = ADD a stimulus - Punishment = meant to DECREASE the behavior - Reinforcer = meant to INCREASE the behavior

### Subject: Algebra

Sam's dad is three times his age. The sum of their ages is 40. How old is Sam? How old is his dad? (Hint: Let x be Sam's age)

To solve this question, you would need to set up an equation. 1) Overall: the sum of Sam + his dad = 40 2) Let x be Sam's age, so x = Sam 3) Sam's dad is 3 times his age, so 3x = Sam's dad 4) Put it together, so x + 3x = 40 5) Combine like terms to find the value of x (Sam's age); x + 3x = 4x 6) 4x = 40 7) Isolate x by dividing 40 by 4; x = 40/4 8) x = 10 9) ANSWER: Sam is 10, and his dad is 30 (3 X 10 = 30)
