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? \( 20+(3 \cdot 4)-2 \)

Let's break this down! Initially, Brooke had 20 pins. Then her cousins each bought her 4 pins. If we assume she has three cousins, that would mean \(3 \cdot 4 = 12\) additional pins. After that, she gave away 2 pins to her best friend. So the expression \(20 + (3 \cdot 4) - 2\) accurately captures the number of pins she has now! Next up, what about solving it step by step? First, calculate \(3 \cdot 4\) which gives you 12. Now add that to her initial 20 pins for a total of 32. Finally, subtract the 2 pins she gifted away, resulting in 30 pins. Easy peasy!
