1)) Brooke had a collection of 20 pins. Her cousins each bought her 4 pins. Shortly after that, Brooke gave 2 pins to her best friend. ()) Which expression tells you how many pins rooke has now? \( 20+(3 \cdot 4)-2 \) \( 20-(3 \cdot 4)+2 \)

Let's break down the problem step by step to determine how many pins Brooke has now. 1. **Initial Collection**: Brooke starts with 20 pins. 2. **Cousins' Contribution**: Each of her cousins bought her 4 pins. The problem states "cousins," which implies there are multiple cousins. However, the exact number of cousins is not given. For the sake of this problem, let's assume there are 3 cousins (as indicated by the expressions provided). - Therefore, the total number of pins received from her cousins is \( 3 \cdot 4 = 12 \) pins. 3. **Giving Away Pins**: Brooke then gives away 2 pins to her best friend. Now, we can express the total number of pins Brooke has after these transactions: - Start with 20 pins. - Add the pins received from her cousins: \( 20 + 12 \). - Subtract the pins given to her friend: \( (20 + 12) - 2 \). This simplifies to: \[ 20 + (3 \cdot 4) - 2 \] Now, let's compare this with the provided expressions: 1. \( 20 + (3 \cdot 4) - 2 \) 2. \( 20 - (3 \cdot 4) + 2 \) The correct expression that tells us how many pins Brooke has now is: \[ 20 + (3 \cdot 4) - 2 \] Thus, the answer is the first expression: \( 20 + (3 \cdot 4) - 2 \).
