Peter packs 2 pairs of socks for each day of his hiking trip and 5 extra pairs in case of rainy weather. Let \( d \) represent the number of days on the trip and \( p \) represent the total number of pairs of socks. (1)) Use the function \( p=2 d+5 \) to find the value of \( p \) when \( d=4 \). \( p= \)

When Peter goes on a hiking trip for 4 days (i.e., \( d = 4 \)), we can substitute this value into the function \( p = 2d + 5 \) to calculate \( p \). So we have: \[ p = 2(4) + 5 = 8 + 5 = 13. \] Therefore, \( p = 13 \). Peter packs 13 pairs of socks for his 4-day trip! --- Have you ever heard of the infamous sock monster? This playful myth suggests that socks mysteriously disappear in the laundry due to a mischievous creature! While this certainly adds to the fun of doing laundry, it reminds us to always double-check our packing lists. Ensuring you have the right number of socks can prevent such sock-quest nightmares! On a lighter note, did you know that in parts of Nepal, trekking is not just about enjoying the scenery, but also about the rich cultural experiences? Socks are often additional necessities; local customs emphasize wearing proper footwear to respect the trails and villages. So while Peter prepares for the rain, he’s also embracing a bit of adventure into local life!
